The problem in the parent's post is that people advocating for "taxing the rich" aren't actually talking about people who are being payed $100K. They are talking about people whose wealth comes from owning property. In that case, I'm not sure that our intuition about the effect of marginal incentives necessarily applies to the same degree. E.g. if a wealthy industrialist decides not to invest in a some piece of capital, it's not as though the capital ceases to exist; it will just be used by someone else. E.g. if an industrialist decides not to invest in a gold mine, then it's not as though the gold disappears. The land will simply be developed by someone else.
