Why focus on a politically fraught issue like taxes/wealth redistribution as a path to addressing issues which are are not constrained by party politics? Surely it would be easier to gain a broad base of bipartisan support for legislation addressing corruption, if corruption is the problem, or concentration of power, if that's the problem. It seems to me that wealth equality is nothing more than a handy wedge issue. The concept of 'fairness' is baked into our monkey brains[0], which makes it easy mechanism for engendering anger, in the hopes of turning anger into votes.
