The owner class is hard, hard right. Like Robber baron grade hard right. The workers are left on social issues, but a lot are still hard right on the economy.
That's sort of the problem. There are lots of folks who are left wing socially (pro-gun control, pro-gay rights, pro-choice, etc) but get real right wing real fast when they think they're taxes are going up. Our Media is left wing on social issues but hard right on economics. Free Trade, Trickle Down economics and Austerity are practically gospel in American media.
Part of the problem is folks look at just about every expense that isn't food as taxes. I've caught lots of folks doing it. Insurance? Tax. Phone Bill? Tax. etc, etc. The other problem is that after the Iraqi War Americans aren't seeing good returns on their taxes. Literally Trillions of wealth was just handed to a lucky few in exchange for nothing. We've let large scale corruption slide for so long that folks have lost confidence in the gov't. They've also forgotten what America was like before the Feds stepped in and started preventing super fund sites from happening (Flint Michigan Water Supply anyone?).
The other problem is Bill Clinton. He moved the country hard right so he could forge an alliance to get into the prez office. Again, left on social issues hard right on the economy. Trump brought up Tariffs but made it a point not to use the "T" word. What's funny is watching all the folks out there who know something is wrong but can't figure out what to do about it pushing Trump and Sanders up in the polls. It's gonna be funnier when Rubio or Bush gets the election despite popular vote thanks to hard right stuff like Citizens United.
Oh, and the colleges have been moving hard right too. Where do you think those $10,000/semester tuition bills came from?
