Last I looked no; the bottom 30% is where Denmark does better than the US. The median wages are similar, maybe slightly higher in the US.

Good question. Probably you have to hit the super rich 0.001% with massive taxes, or an aggressive estate tax (preventing wealth from accumulating across generations).

But even with that, good regulation that facilitates competition is probably necessary. I wouldn't be surprised if that makes a bigger splash than the top 0.001%.

Note: there is good and bad regulation. Denmark is heavily regulated, but a lot of it is efficient and fosters competition.
