You're acting as if getting that blue collar training is something people are rejecting.

The people who are truly broke don't have the option of choosing between a history degree and plumber training. They grow up in broken homes with parents working 3 part time jobs because no one will give them benefits. The benefit cliffs prevent their parents from jumping up in social status.

"The only people I see are struggling are the ones who have made dumb choices" is naive at best, dismissive, callous, and uncaring at worst.
