Taxes are high because of all the money democrats waste on their illegal aliens they let in across our border buying their illegal vote. Plus, all the fraud they overlook. Having said that, I will admit that before Trump the Republicans didn't do anything about it, and that makes them just as responsible for the fraud as the democrats are.
However, if you want to know just what the democrats goal is for this country: Look up "HOW TO CREATE A SOCIALIST STATE" by Saul Alinsky. The democrats have all 8 levels listed in their play book.
