Propping up housing prices and NIMBYism isn't trying to give your offspring a better life.
I guess by some math they would leave the house to the kids, but that will be when the Boomers are ideally 80 and their kids are already grandparents. Assuming the wealth isn't spent on end of life care (it will be).
A lot of people seem to think that withholding vaccines and using low fuel efficiency SUVs to transport their kids is giving them a better life, I don't have much hope of them considering broader economic outcomes. But they will sacrifice others' outcome (not to their face though) if they think it will further theirs even a little bit.
