If I think about everything I've learned about the world since I was a kid, the thing that would've most surprised kid-me is how privileged the median or even 10%-ile person with a "good" job is, e.g., what's the rate of tech folks at top companies who were too poor to get dental care and have crooked teeth?
1/1000 seems like the right order of magnitude for someone my age or younger in tech and maybe it's 1/100 but, at a population level in the U.S., seems more like 1/5 or maybe 1/10.
