I once stumbled on a rant by a post doc CS student. In addition to an essay why being able to do type erasure is good and why actually doing type erasure is terrible. He had an essay with the observation that while capital has the ability to pull their money and reinvest it elsewhere if they dislike returns and risk, skilled workers are kinda stuck with whatever skill they've invested in. And capital can diversify while a worker usually is stuck with exactly one investment. Given that it seems shitty to give capital better tax preferences than earned income.
