No it hasn't.
A couple of things:
--we kept this country running pretty fucking well for about 80 years with "the rich basically paying for everything" and wage rates for middle class at steady, reasonable CoL growth.
--No one is demanding that "the rich pay for everything."
Again. we have the vast majority of the money. Why do you think massive new taxes are necessary when we already waste shitloads of money on garbage things that benefit no one?
Cleaning up government spending is something true conservatives have been touting for the last 20+ years.
The problem? It never happens. It only becomes a more bloated whale. This is because there isn't an unbias entity in our government system that says "Our military is taking too much money, we need to cut the budget".... In comes the equivalency of a corporate lobbying campaign to ensure that they send the message to the people in office that "No, you NEED this military budget. It is ESSENTIAL. It will also HURT YOUR CHANCES OF GETTING RE-ELECTED!" and thus the bloated pig continues to get bloated year over year.
Sure, we can totally crack down on our healthcare and reduce costs across the board in order for us to have a better system that is single payer (or whatever your preference is). The problem is that our government system is a piece of shit because we will never ever trim the fat. It will only become more and more and more bloated.
Also no idea where you get the message of "the rich basically paying for everything". That certainly has not (and has never) been the case in the last 80 years.
And yes, they are actively campaigning under the general guise of "THEY need to pay more". It's never "WE need to pay more".
