The point about "billions" was about proportions: for everyone like you or me, there are 1-2 other people on this planet living under radically different familial expectations. They don't need to all be working at tech jobs on tech salaries; it only needs to be the case that a substantial proportion are (which is true).

I don't know how old you are, but it sounds like your parents benefited from a substantially more worker-friendly economy than most people in my generation do. Put another way: it's fantastic that your family was able to get you the help you needed, but I don't think that you experience is repeatable in 2023 ("keeping up with the Joneses" or not).
