This tax strategy aggressively pursued during the Reagan administration, supported during the Clinton administration, and maintained during the Bush and Obama administrations relies on the assumption that growth among the asset-holders translates into more jobs and better pay for everyone ("trickle-down economics"). This assumption seems asinine now because of course the wealthy are going to save whatever profit they make. That's how the wealthy get wealthy in the first place! The Great Recession has only exposed this more. Employers realized "Actually, I didn't need those positions anyway." Other employers realized "There's enough demand for jobs here, so I don't actually have to increase salary that much." Property values may have collapsed during the Great Recession but a lot of long-term property owners realized "People still need a roof over their heads. Demand for rent is at an all-time high. I have no incentive to lower rent."
Consequently, wealth inequality grows. Wages stagnate. Homeownership stagnates. Rent rises with inflation. The percentage of 25- to 34-year-olds living at home with their parents is the highest it's been in nearly a century. The young and educated see the situation, realize that they have no power over an establishment bending to the whims of the upper-class and corporations, and grow more and more apathetic. The old and uneducated are fed populist nonsense and anti-immigration scapegoating, thinking that driving out the brown people will get them the jobs and pay that employers have no interest in giving them. Trust is an emotion. A belief. What makes you less likely to trust others? Insecurity. And why wouldn't people be insecure in this economic environment?
(I realize that this is a very U.S.-centric comment and I apologize to any other nationalities for whom this does not describe the political environment.)
