I think you're still missing the point. These families can't afford to live in Nebraska either. You repeatedly phrase your family as being different from these people, your family knew what to do and made temporary sacrifices for a better long term success right? And these families just lack the grit or determination or smarts or whatever of your family right? Have you considered these families are doing the same thing as your parents? That they're making the same calculations your parents made but that the Bay area is still a better scenario for them? That your family isn't really that different from these families? Moving from a SV Chipotle to a Lincoln Chipotle is great until I try to figure out what to do with my 2 year old son and realize all the gains I've made and more will be eaten up by childcare bills that my mom/grandma in SV could have done for free. Moving isn't some inherent good that magically makes you better off, it's a calculation: just because your parent's calculation came up with "Move" doesn't mean these people doing the exact same calculation are going to come up with "Move."
