My not-very researched take: entrepreneurship is a game played mostly by people from already wealthy families. Since the % of wealthy people in the US is higher, and their rich are richer, you get more "initially rich" entrepreneurs.

Interesting take but how do you explain almost half of all companies being founded by immigrants or their children?

A lot more than half of Americans, if they were born in another country, would not be allowed to immigrate to the US under modern immigration policies.

Most immigrants have to undergo an extremely strong selection filter, before they are allowed in. It would be truly surprising if they weren't more successful on a per-capita basis.

Are those poor immigrants, or rich immigrants?
