What’s the link between middle class and conservative values?
In my area (urban, northeast) “middle class” families tend to have a parent who is either a union member (teacher, healthcare worker, etc.) or “union adjacent” and they are often very progressive. They tend to work with a highly diverse group of colleagues (or patients, or students, or customers) and they are quite accepting of lots of differences.
The conservatives lean upper income. Either inherited wealth (and they want to keep every penny that great grandpa accumulated) or “self made”, and they’re happy living in a bubble, meeting other rich people at their club, having their kids attend prep schools with other rich people, not really knowing people who struggle except for their domestic staff or the landscaper who (they assume) knowingly hires undocumented workers but as long as they show up on time, they’ll look the other way.
