All of that is correct, or near enough that there's no reason to quibble over it.
Again, though, the point of comparative statics is to think through what effects a particular change will have on a particular factor. This means we are starting from the current situation and modifying it in some marginal way. America is nowhere near the cases you're describing.
The purpose of this post was to point out that people aren't carefully thinking through their rhetoric on income taxes and they're saying contradictory things, and then explain what's going on economically.
I understood your point from the beginning, my argument was that its a too much restricted and short-lived stance so that it's not meaningful enough to relativize things or put the affirmation of "taxes disincentivize work" to test.

Ok, I remain unconvinced of that, while granting that you raised interesting points.
