The main sufferers have been what is used to be called the industrial workers, they are now saying that if you can’t protect us, we are going across to the people who might be able to. They might be ugly but they might allow us to throw a political hand grenade into the system to wake up those Americans who have been neglected ideologically by the left and also because they have actually lost their jobs to benefit people in China, as Trump has been arguing.
Job loses to offshoring and job loses to global labor arbitrage are totally different beasts altogether.
