>Speaking as someone who's been a super high performer in some roles, and a terrible performer in others, I definitely want to reduce inequality. Like, it's entirely unfair that I (because I negotiate well) get better options than others.
Then give your money to people who don't negotiate as well. In practice, you don't: your revealed preference speaks louder than your stated preference does.
Wanting to live in a better society should not preclude me from doing better in this one.
And the transaction costs on such an approach would be too large, as I'm sure that you know.
M I note that you don't address the notion of context dependent high performance.
