RE: "... a complete disincentive to succeed and earn over $200k as the government is entitled to more of it than you are."

I don't know anyone who has said to their employer or their employees, "whoa, I'm getting too successful here. The last thing I want is to break that $200k barrier."

After $200k, you pay a marginal rate of 33%. Under that, you pay 29%. Not a massive disincentive.
