Definitely the 10th. State governments should have next to no power.
That is where you are sorely mistaken. I'd say the 16th and the 17th equally. The states are meant to be a check on federal power. That's how duel federalism works. I get your desire for massive federal power but it's proven to massively fail in terms of civil rights and liberties.
Jim Crow
The federal government got some of it wrong. Like forced bussing and affirmative act. Weren't those struck down as unconstituitional?
The states got
vastly more of it wrong.
Like Jim Crow. Wasn't that struck down as unconstitutional?
