So here's a of income inequality in the United States over the last few decades. The "progressive taxation" that you seem to think is killing the country, by definition, takes more money away from rich people than poor people. Yet rich people are getting richer, and poor people are getting poorer. The economic conditions you seem to be so worried about, the taxation regime you're complaining about, is one that's making the rich richer and the poor poorer, so clearly progressive taxation isn't doing shit.
That graph shows, simply, that the rich are earning more and contributing less. Seriously, how the fuck can you look at a graph like that and say, yes we need to vote for the bankrupt orange fascist rapist and tax the rich less! That will solve all our problems! It beggars belief. Good luck.
