That's true to an extent but I think that problem increases as that salary (or, more likely, capital gain) increases. So just limiting total wealth increases would likely reduce the temptation to sell out.

Well, sure, but that limitation is very much contrary to capitalism. A very good idea, but definitely moving away from capitalism.
