2023 July 13 @NEJM Clinical Decision section on Treating Intermediate Risk PE: CDT and thrombectomy not even considered. They are arguing systemic TPA versus heparin! I had to double check the date to make sure it wasn’t the 2008 issue

Robert Reich forgot the 6th and most common way:
6) Build something millions of people actually want
There are basically 5 ways to accumulate a billion dollars:
1) Profiting from a monopoly
2) Insider-trading
3) Political payoffs
4) Fraud
5) Inheritance
Don’t believe the self-made myth.
Readers added context they thought people might want to know
Research shows most billionaires accumulated wealth by founding and building successful companies. A University of Chicago study found 69% of the 2011 Forbes 400 started their own businesses.

Elon Musk just defended America better than every politician in Washington combined.
Musk: “After World War 2, the US could have basically taken over the world and any country. Like we got nukes, nobody else got nukes. We don’t even have to lose soldiers. Which country do you want?”
One nation on earth held a weapon nobody else had.
Total dominance. Zero competition. No risk of retaliation.
Every empire in history that held that kind of advantage used it.
Rome. The Mongols. The British. The Ottomans.
They conquered until they collapsed.
America had a bigger advantage than all of them combined.
And it rebuilt the countries it just defeated.
Musk: “The United States actually helped rebuild countries. So it helped rebuild Europe, it helped rebuild Japan. This is very unusual behavior, almost unprecedented.”
Almost unprecedented?
It had never happened before. Not once in 5,000 years of recorded history.
The Marshall Plan wasn’t foreign aid.
It was the most radical act of restraint any superpower ever committed.
America turned its enemies into allies. Turned rubble into economies. Turned surrender into partnership.
Germany went from ashes to the economic engine of Europe in a generation.
Japan went from unconditional surrender to the third largest economy on earth.
Three years after the war, America was flying food into Berlin.
A city in the heart of the nation that just tried to destroy it.
That’s not policy.
That’s a civilization deciding what it is at the exact moment it has the power to be anything.
You’re being told a story right now.
That America is the villain of history.
You hear it everywhere. Media. Universities. Social platforms.
Musk: “There’s always like, well America’s done bad things. Well of course America’s done bad things, but one needs to look at the whole track record.”
Every nation on earth has dark chapters. Every single one.
The difference is what a country does when nobody can stop it.
And when nobody could stop America, it fed its enemies and rebuilt their cities.
Musk: “The history of China suggests that China is not acquisitive. Meaning they’re not going to go out and invade a whole bunch of countries.”
Probably right.
China has historically built walls, not fleets.
But the real question isn’t about borders anymore.
We’re approaching a moment that mirrors 1945 in ways nobody has fully processed yet.
AI is going to give a handful of people a power advantage that makes nuclear monopoly look quaint.
If someone is going to hold that kind of power, who do you want it to be?
The country that conquered when it could? Or the one that rebuilt when it didn’t have to?
Every alliance. Every trade route. Every economy.
Billions lifted out of poverty.
All of it traces back to one act of restraint that had never been done before.
And carries no guarantee of being repeated.
The most powerful thing America ever did wasn’t building the bomb.
It was what it didn’t do after.
Mark Cuban just described the largest wealth transfer of the AI era.
Almost nobody understood what he said.
Cuban: “There are 33 million companies in this country. Aren’t going to have AI budgets. Aren’t going to have AI experts.”
Not tech startups.
The shoe store. The regional trucking outfit. The accounting firm with 12 employees.
The businesses that actually run the physical economy.
They know AI is coming. They have no idea what to do with it.
Cuban: “You’ve got the head of Microsoft saying software is dead because everything’s going to be customized to your unique utilization.”
Software is dead.
The SaaS era ran on one rule. Build a generic product. Force millions of companies to bend their workflows around it. Charge rent forever.
AI ends the contract.
The business stops bending to the software. The intelligence bends to the business.
But customized by whom.
The third-generation manufacturer cannot tell Claude from Gemini. The county hospital is staring at a reactor asking where the light switch is.
Cuban: “Who’s going to do it for them?”
That question is worth more than the frontier models themselves.
Hundreds of billions are being burned to build the foundation. The smartest engineers alive are locked in a bloodbath over who owns the base layer.
Let them fight.
Let them burn the capital. Let them drive the cost of raw intelligence toward zero.
Because the wealth does not collect where the brain is built.
It collects where the brain meets the business.
Every ambitious kid in college right now thinks survival means a seat at OpenAI or Anthropic.
Cuban is staring at the other 99 percent of the economy.
Learn the models. Then learn the messy, unglamorous reality of how a 50-person company actually operates.
Walk through the door. Understand their problems. Wire the intelligence directly into their revenue.
That is not a job title. That is an entire economic class being born.
You do not need to build the brain. You need to build the nervous system.
The biggest winners of the electricity era were not the engineers who built the generators. They were the ones who walked into dark factories and showed the owners where to plug in.
33 million companies are standing in the dark right now.
Silicon Valley is racing to build the god. The fortunes will belong to whoever teaches him a trade.
This is unbelievable, huge change is coming to media in the next three years.

Why the U.S. Healthcare System is Not Capitalism
Capitalism rewards competition, choice, and consumer power.
The U.S. healthcare system, on the other hand, rewards monopolies, confusion, and regulatory loopholes.
What we have today isn’t capitalism—it’s a Frankenstein monster of government interference and corporate favoritism.
Here’s the breakdown:
1. Barriers to Entry:
Killing Competition Before It Starts
In a capitalist system, new businesses can challenge the old guard by offering better products, better service, or better prices.
In healthcare, though, that’s a pipe dream.
Take Certificate of Need (CON) laws, which require healthcare facilities and physicians to obtain approval from a state committee before opening new facilities.
These laws were supposed to reduce unnecessary spending, but in reality, they give established health systems a monopoly by preventing competition.
And let’s not forget the ACA moratorium on physician-owned hospitals. If you’re a doctor who wants to open a hospital that puts patient care above profits, you’re out of luck.
It’s like outlawing new restaurants to protect fast-food chains.
2. Opaque Pricing:
The Anti-Market
Capitalism demands transparency.
When you buy a product, you must know what it costs. Healthcare turns that idea on its head.
Imagine walking into a car dealership and being told, “We’ll send you the bill after we talk to your employer and your car insurance company.”
That’s how healthcare pricing works.
Health Systems hide their prices behind secret contracts with carriers, and patients get hit with surprise bills for services they didn’t even know they received.
You can’t shop for the best price if you don’t know what the price is.
3. Third-Party Payers: The Death of Accountability
Capitalism relies on a direct relationship between buyers and sellers.
In healthcare, the buyer (you) is completely disconnected from the seller (your doctor).
Why? Because your insurance company or employer is footing the bill.
When someone else is paying, do you care what it costs? Do you even know what it costs? Of course not.
That’s why health systems are paid $5,000 for an MRI and an independent imaging center is paid $400. No one’s watching the store.
4. Regulatory Capture:
Rigging the Game
If capitalism is a free market, then healthcare is a fixed fight. Big insurers, pharmacy benefit managers (PBMs), and health systems spend billions lobbying the government to write rules in their favor.
PBMs, for example, negotiate “rebates” from drug companies and keep the savings for themselves. Insurers make money by denying claims, not paying them. Health systems consolidate smaller practices, eliminating competition and jacking up prices.
This isn’t capitalism—it’s collusion.
5. The Illusion of Choice
Capitalism thrives on choice:
If you don’t like one physician, you switch to another. But in healthcare, your choices are dictated by your insurance network, your employer, or the government.
Want to pay cash for a surgery?
Good luck.
Many health systems won’t even take it because they’re locked into the insurance game.
What’s Really Happening?
The U.S. healthcare system isn’t capitalism.
It’s cronyism, cartel behavior, and bureaucratic meddling. It’s a system where competition is suppressed, consumers are kept in the dark, and a handful of players profit at everyone else’s expense.
Capitalism:
•Open pricing: So patients could compare and choose.
•Open competition: So new players could challenge the incumbents.
•Direct relationships: Between patients and doctors, cutting out the middlemen.
What we have now is the opposite. It’s a rigged system that protects the powerful and punishes the rest of us.
Think About This
If healthcare were capitalist, you’d know the price of an MRI before getting one.
You’d be able to choose between competing hospitals, doctors, and surgery centers.
And the best care at the best price would win.
But right now?
You’re not a consumer.
You’re a hostage.
Capitalism isn’t the problem here.
It’s the solution.
“It is hard to imagine a more stupid or more dangerous way of making decisions than by putting those decisions in the hands of people who pay no price for being wrong.”

This is an easy fix.
Restore physician independence and ownership.
Of course doctors want to clock in and clock out when they are employees of a large faceless health system. They have no ownership. Care is led by administrators. They feel it is just their job to be data entry clerks, upcoding notes and answering CDI queries to maximize revenue. Show up, glue yourself to the computer for 12 hours, leave...
Restore physician independence and ownership and that problem goes away.
There are policy solutions to restore physician independence. All our professional societies and organizations need to back these policy efforts:
Site Neutrality
340B Reform
Regulatory burden reduction
Quality metric reform
Reversing the ban on physician owned hospitals
Stark law reform
Then we can get back to physician-led care.

"Price gouging" is a virtuous act of delivering goods at market rate, when they are needed most.
Should water cost $100 per gallon? Yes, when nobody is offering it for less.
And when water is selling for $100 per gallon somewhere today, guess what will happen tomorrow? Every gouger in the region will be rushing water to where it's needed most.
This concept is so simple, so elementary to economics, and yet nobody in positions of political authority ever acknowledge it. Kamala here wants to punish people for it. Trump would say the same, if he were President.
And when these simple concepts are misunderstood so widely, imagine the difficult ones.
These people do not deserve to rule us.
