On that scale the people you empathize with are doing spectacularly well, and have plenty of options. Once wages go up the local economy develops a middle class and becomes self sustaining companies may move on to the next low wage country but the effects remain.
That not everybody in a single country benefits from this (especially not the blue collar workers in the wealthier countries, especially those unwilling to adapt) is sad, but as much or more caused by automation than by work flowing to low wage countries. The disparity is so great that that work will not come back, no matter what.
Whatever was wrong with the DNC that it forced you to vote against your interests and those you claim to care for is beyond me, I just can't follow that kind of reasoning. Hillary Clinton was far from the ideal candidate but she'd be immensely better for your country than Trump is, and everything that has happened so far has both underlined that and has more or less been predicted beforehand.
Make no mistake: Bannon et al are out to destroy the United States as you know it to reshape it in to a much smaller pond in which they are the bigger fish.
Sow wind, reap storm.
