They want to deconstruct the government. It's the natural progression of a movement that started with Barry Goldwater. They have a fundamental cynicism towards government and a hostility towards pluralism and "the common good". They dabble in White supremacy. Nixon and Reagan were both racist. We know where Trump stands. They want to disenfranchise Black and Latino people, keep Native tribes oppressed, and if they can torpedo public education, that's a big step toward achieving that.
They want us to pay for education and healthcare and they want the profits. If you can't afford it, good luck. They want to kill the postal service, public television/radio, They want our social security money too and who will stop them? They want a Mad Max style future where might and money make right and all the little people battle for resources. Climate change will make things even worse.
Happy days!
