Piketty's writing doesn't apply to the US. His work applies to Europe, where legacy far outweighs entrepreneurship.

And yet it's the US where wealth inequality is higher.

It's easy to fall for that liberal meme, but you (and they) are wrong. Pickety explains it in his book.

In Europe, most wealth is inherited, and power in concentrated in family dynasties.

I don't get your point and your focus on inherited wealth vs. entrepreneurial wealth. Even if most wealth in America is not inherited, a wealth tax wouldn't inhibit entrepreneurship.

If you have, say a $200K minimum threshold to start owing minimal annual tax, and a progressive scale after that, do you really think it would stop the next Bill Gates?

I encourage you to read Pickety's book. He argues that inherited wealth is bad because it rewards people for being born.

Why would anyone, including Pickety, want to prevent Bill Gates?

I feel like we're talking past each other at this point, so I'll drop off this conversation.
