The average medieval peasant was illiterate, slept on straw, had to work if they were sick and God forbid they broke a bone they would likely have the bone set incorrectly handicapping them to varying degrees for the rest of their life.

The average American has air conditioning, electric or gas heat, a smartphone, watches television several hours a week and rarely has to worry about food poisoning or getting intestinal parasites.

Give up the air conditioning, the car, the 3000$ laptop every 2-3 years, the 1200$ smartphone every 18-24 months, the Netflix/Hulu/Disney+/Spotify subscriptions, never purchase a single item that is (or contains a component that was) imported, the exotic vacations 0.5-4x a year, the 4-9$ cup of coffee 1-3x a day and that food delivery service you use 1-7x a week, running water and all electricity at your residence and you too could work considerably less.
