Correlation doesn't mean causation. The blue collar workers of America have lost purchasing power. That is a fact. Chinese factory workers are better off, that's another one. But blue collar workers from other countries are better off than their American counterparts. How's that possible?
Health care, education, name it and you will see that don't work anymore. War again drugs, a complete disaster. But that's because the 0.1% stopped paying their fair amount of taxes and have converted the public services into their own private business in name of a "small government" while these same rules don't apply to them because they are "too big to fail". And has nothing, or little, to do with Chinese factory workers. Americans have voted for their own government to not help them anymore. It is not just poor people that suffer that lack of services but all the general population, except for the 0.1% that has money to pay for it all.
America have grown a lot in this past years, redistribution of wealth has failed. The 0.1% talks about not wanting a "class warfare" while fighting one.
Everything is linked in the economy. When I say that it's come at the expense of these workers, I don't mean somebody made the call to take money from them and give it to Chinese workers. I mean that in the grand game of musical chairs, they are the ones who have been left standing.
Have you seen the elephant graph? [0] The reason people are upset is not because they are selfish, it's because the people above them are. The wealthiest of the wealthy 0.1% have profited immensely, the lower half of the world's population has been lifted out of poverty, and this has all come at the expense of the American blue collar worker. Factories have closed, the opioid epidemic has claimed tens of thousands of lives, and everybody is calling these suffering people selfish and lazy. It's no wonder they want to give everyone the middle finger and vote for Trump.
