But they entered their field with the union already established. Humans won’t fight for a damn thing.

Ok? That has nothing to do with my comment pointing out that "comfortable middle class suburban" != anti-union and anti-labor.

I know plenty of people in the trades that are anti-union - they're typically the ones in the "comfortable middle class suburban" category. They've worked a bit and maybe are contractors of their own. They complain about how much it costs to have a union crew and about how slow the work gets done. They do not think workers need more protections (look at Florida and other states prohibiting mandatory water breaks for worker protection), and actively complain about needing to carry Worker's Comp insurance and withhold taxes (which is why many of them pay under the table for non-union work, undocumented day laborers outside of Home Depot/Lowes seem to be their favorite choices).

In fact they tend to be some of the most anti-union, anti-labor folks I know.

I will grant that not every single person in the "comfortable middle class suburban" category is anti-union / anti-labor, but it's a pattern I see often enough that it is worth remarking on.
