The Billionaire Thought Experiment

Here's one that really breaks people's brains, so let me lay it out carefully.

Take the richest person alive in 1900. Let's say it's Andrew Carnegie or John D. Rockefeller. The wealthiest human beings who had ever lived up to that point, with fortunes that in today's dollars would rival or exceed the richest people on Earth now. Rockefeller's net worth at its peak has been estimated at over $400 billion in today's money — richer than Elon Musk or Jeff Bezos. The man had functionally unlimited wealth by any standard.

What could his money buy him?

What a Billionaire Couldn't Buy in 1900

No air conditioning. AC wasn't commercially available until the 1920s and didn't become common in homes until the 1950s. Rockefeller, worth hundreds of billions in modern terms, sweltered through New York summers just like everyone else. Maybe he had a nicer fan. Maybe he retreated to a country estate. But precise, push-button climate control? Didn't exist at any price.

No antibiotics. Penicillin wasn't discovered until 1928 and wasn't widely available until the mid-1940s. If Rockefeller got a bacterial infection — a cut that turned septic, pneumonia, a urinary tract infection — he had the same odds as a pauper. All his billions couldn't buy him a drug that hadn't been invented yet. His grandson died of scarlet fever in 1901 — a disease that today is treated with a $4 prescription of amoxicillin from any pharmacy on Earth.

No modern anesthesia for most procedures. General anesthesia existed in rudimentary form, but local anesthetics like Novocain weren't available until 1905. Surgical anesthesia was unpredictable and dangerous. A dental procedure in 1900 — even for the richest man on Earth — involved a level of pain that would be considered malpractice today.

No television. No Internet. No smartphones. No streaming. Rockefeller's entertainment options were books, live theater, the newspaper, and the occasional phonograph — a device with sound quality that would make a modern dollar-store speaker seem like a concert hall. If he wanted to hear a specific piece of music, he had to either own a phonograph cylinder of it (limited catalog) or hire live musicians. You open Spotify and have access to essentially every recorded song in human history. For $10 a month.

No commercial aviation. If Rockefeller wanted to go from New York to London, it took a week on a ship. A week. Each way. Today, a middle-class family books a flight on their phone during lunch and arrives in seven hours. Rockefeller, for all his billions, could not have gotten to London as fast as you can. He couldn't have gotten to Los Angeles as fast as you can. The concept of "I'll be there tomorrow" across continental distances didn't exist.

Rudimentary dentistry. Dental care in 1900 was, to put it gently, barbaric. No Novocain until 1905. Limited anesthesia. No fluoride treatments. No modern fillings. The richest man in the world had worse dental care than a kid on Medicaid in 2026. His teeth probably hurt most of the time. So did everyone's.

No modern surgery. No transplants, no laparoscopic procedures, no MRIs, no CT scans, no ultrasound, no cardiac catheterization. If Rockefeller's appendix burst, the surgery to save him — if it was even attempted — had a horrifying mortality rate. Today it's an outpatient procedure. You're home the same day. In 1900 it could kill you as easily as the appendicitis itself.

No reliable contraception. No safe, effective birth control until the Pill was approved in 1960. Rockefeller's wife had no more reproductive autonomy than a peasant woman. The wealthiest family in America had the same options as everyone else: abstinence, withdrawal, or hope.

What the Average American Has in 2026

Climate-controlled home with heating and cooling that adjusts by the degree. Hot water on demand, 24 hours a day. Rockefeller had servants stoking coal furnaces. You have a thermostat and a water heater that cost a few hundred dollars and run themselves.

A smartphone that contains more computing power than everything NASA used to put humans on the moon — combined. Access to essentially the entire sum of human knowledge, free, in your pocket. Video calls to anywhere on Earth, for free. Navigation that knows every road on the planet. A camera better than anything a professional photographer owned in 2000. Rockefeller had a library. You have all of them.

Hundreds of channels of on-demand entertainment. Every movie ever made. Every song ever recorded. Every book ever written, available for download in seconds. Podcasts on every subject imaginable. University lectures from MIT, Stanford, and Harvard — free. Rockefeller had a piano in the parlor.

Vaccines and antibiotics for diseases that killed millions in his era. Surgical techniques that would look like science fiction to a doctor in 1900. If you walk into an emergency room in any American city tonight with a burst appendix, you have a survival rate above 99%. If your kid gets strep throat, you drive to a pharmacy and it's cured in 48 hours.

Grocery stores with fresh produce from six continents, available year-round, at prices that consume a smaller share of your income than food ever has in human history.

The average American household spent about 30% of its income on food in 1950. Today it's under 12%. And the quality and variety is incomparably better. Rockefeller could eat well — but he couldn't eat a fresh mango in January in Ohio. He couldn't get sushi, pad thai, Ethiopian injera, or a poke bowl. You can get all of that delivered to your door in thirty minutes.

Commercial aviation that gets you anywhere on the planet in less than 24 hours for a few hundred dollars. Rockefeller couldn't buy that at any price.

A car with GPS navigation, collision avoidance, climate control, a sound system that would rival a professional recording studio from the 1970s, and a safety record that makes a 1900s horse-drawn carriage look like a death trap — which, statistically, it was.

Better healthcare. Better food access. Better entertainment. Better transportation. Better communication. Better comfort. Better safety. Better dental care. Better reproductive options. The gap isn't even arguable. It's not a matter of opinion. It is measurable, documented, and overwhelming.

A billionaire in 1900 would trade his entire fortune for a course of antibiotics if his child was dying of an infection. And he wouldn't be able to buy them, because they didn't exist yet. That single fact should reframe every conversation about whether things are "getting worse."
