Progressive taxation would be a bandaid solution in my opinion but, maybe I'm being dramatic. Solidarity economics sound great as a shift in production.
The point I suppose I failed to make. In order to reverse course and affect radical change, you would need to enact taxation policies (FBI style raids on penthouses, IRS investigations into corporations, ICE style black bagging of CEOs etc.) that would be heavy handed. The heavy handedness one would think of when a regular person, like myself, misuses the term "authoritarian".
