A professor my wife had in her feminist studies class confided in my wife that she enjoyed having her in class (my wife leans conservative), because she (the professor) had gotten tired of the bubble. Her professor was raised lower-middle class and spent many years in trucking before entering academia, and was just tired of the constant echo chamber that academia has become. This woman seems to have done the opposite. Good for her.
For me personally, despite being in tech in a well paying job, at my church and at various volunteer groups I'm part of, I am exposed to people of all backgrounds. And of course, growing up middle class and seeing how my friends and family behaved, I feel way more comfortable among what I consider 'normal' people. It's like two different worlds at work versus in person. Luckily, I'm now at a chipmaker where people seem more level-headed. Something about having to interact with physical constraints makes people more moderate I think. The SW startup world is so far off the rails, I found it difficult to relate.
