Income Disparity

The Inspiration

In a 2023 lecture on microeconomics at MIT, professor Jonathan Gruber commented that:

America is the most unequal major nation in the world.... The top 1% of Americans control 25% of all the income in the U.S., which is at least 5% higher than any other major nation in the world.

Which nations do we typically compare with America?
