The title may be a bit overstated, but I think the separation between low income working class people and those in more high paying professional jobs is pretty real. I grew up in a rural area, paid for college by serving in the military, then hustled my way into tech (like lots of others). Very few of my friends from high school or the military have had similar luck getting a stable job. When I talk to my current tech coworkers about anything that was very normal as a child (hunting, owning guns, working 20-30hrs a week after school, etc) - its like we are from different planets.

This was on PBS a while back, I think it gets at some of the differences pretty well: https://www.pbs.org/newshour/economy/do-you-live-in-a-bubble...
