The plight of the working class is about free trade and reprioritizing economic policy. Union busting sent business to the South, NAFTA sent it packing.
Now even high end service jobs are at risk. A local hospital voted to unionize, and immediately afterwards the ER fired everyone and ships in visiting nurses from 400 miles away. It keeps the local labor hungry and costs down in the long term.
Shameful behavior was the choice of the USA's white working class: They had the choice between prosperity without racism, or immiseration with the continuance of racism. They chose the latter. They voted against pro-growth policies because those policies were promoted by a political coalition that was also committed to extending prosperity to every citizen, regardless of race.
I made $12/hour as a "forklift operator" in 1993, just as a point of reference. And I doubt a modern college student could even get hired for a forklift operator-type job.
