The difference between a peasant and a king in the middle ages, and a peasant (e.g., a worker today) and a king (e.g., Bezos, or the Saudi king) is night and day.

A middle ages peasant has access to a tiny sliver of the goods and services available to the king. A modern day peasant has access to pretty much all of the goods and services available to Bezos today. It's not like the food Bezos eats is any better than any body else's. The clothes he wears is not much better than anybody else's. The computer he uses is not much faster than anybody else's.

So the gap in availability and access of goods and services between the rich and poor is lower today than it was in the past.
