At some point, there's going to be another inflection point where a lot of people making comfortable upper middle-class incomes move out to, well, anywhere. Basically, someone's going to do the math, and recognize that remote workers are just as productive, and are a little cheaper then having a bunch of 20-somethings in the office physically. And the incentive for anyone who wants to have kids to work remote is just going to be really, really high.
We may also see more software engineers sticking around as engineers instead of becoming managers as well. Because the incentive to grow your income via management may be relieved.
