Most of this is the 401k argument, which is an irrelevant criticism of my source, not an argument made by your source.I cited the arguments previously and quoted myself last fucking post.
So what's left... you're just talking about the "US citizens are disadvantaged" bit then? I mean, you made that argument with zero detail, which is why it went unaddressed.
It would disadvantage American citizens... with over 100million in wealth (fewer than 10k people). Every other American citizen, even almost every millionaire? Perfectly level playing field. And frankly, I don't really care about disadvantaging centimillionaires slightly. It's not as if this would put them out of competitivity. They'd still have more financial clout than everyone else.
