I agree that this is a huge driver for Trump's popularity and exactly why I said what I said above. Trump can just brand Hillary as a career politician and be typical Trump, "do you really want another career politician like the past X years? Are you happy with the job your politicians have been doing for the past X years?" and it will resonate with people. People are just SICK of politicians. Approval ratings are ridiculously low. People want change (on both sides even, you saw this with the surprising popularity of Bernie in the primary).
I get the motivations. It's just sad b/c of how misdirected they are.
Trump's voter base is overwhelmingly white, uneducated males (there are polls on this).
So, why are white, uneducated males so angry?
Whether they realize it or not - trickle down economic theory, endless attacks on unions (which protected their jobs and wages), globalism, and money in politics are the biggest culprits.
The sad part is "burn it to the ground" does nothing to help them. America is still the world's top economic player. Burning things to the ground won't change that for the better. Reductions in civil liberties and diminished status in the world is not a solution.
The Republican Party has endlessly tried to drive down wages/rights of the blue collar class, but at the same time, globalism has done the same.
Globalism is not going to change in their favor. Economists have shown that over the tens of millions of manufacturing jobs lost, we'd get maybe at max 2 million back by tearing up all of our trade agreements (while we could lose just as many by making American companies less competitive). And some economic trends (i.e. a move away from dirty coal) aren't going to reverse.
So what can they influence?
You want to get money out of politics? Start by supporting the party that wants to do the same and overturn Citizens United.
You want to see jobs created by much needed infrastructure improvements? Vote for the party that wants to do that.
You want to have more of a social safety net that can help you get educated, get health insurance, improve Social Security? Vote for the party that wants to do that.
You want to get paid more? Vote for the party that wants to raise the minimum wage.
Voting for Republicans is the literal embodiment of cutting off your nose to spite your face.
Again... none of this prob. matters, b/c it's all about fear and anger and hate feelings and blaming others, sadly. Sigh....
