This is because economists are shills that collect their paychecks from the rentier class or their cronies. People that actually understand markets and business don't work as economists, they are too busy getting rich by trading or creating. Unearned income is obviously a net economic drag. I'm not saying there shouldn't be any, I want to retire some day too. In fact in German the word for retiree is "rentner." The problem comes when there is a permanent rentier class that simply extracts rents from the working economy. They are parasites. Most of the valid criticisms of capitalism are actually just criticisms of excessive rent-seeking. And that can exist under any economic system.
