I mostly agree with that answer, although think that there are virtually no politicians pushing it: those that want to cut one tax want to cut the other two, rather than a revenue neutral adjustment.

Doesn't it create some kind of weird cross-border investing incentives though? I.e. we drop the corporate tax in the US, we could raise the income tax to recoup some of that, but not all of it, due to foreign investors who get taxed in their home countries.
