Here's how this is actually gonna work, at a broad social scale:
With some rare exceptions, the Boomers will sell their homes to pay for medical expenses, and die alone, in either old folks homes, hospitals, or much smaller homes/apartments, or if they're very lucky, homeless or in a concentration camp for the homeless.
They'll have to sell their homes because private equity/credit is imploding, and all their pensions and 401ks are ultimately based on that, even if they say they're not.
And home prices are crashing because:
1 younger generations don't get paid enough;
2 climate change costs are finally coming due via insurance now actually reflecting climate risks + outsized proportion of the last ~2 decades of new homes being built in high climate risk areas;
3 property tax rates are skyrocketing due to decades of local government mismanagement of budgets and infrastructure.
A fun fact that people do not like to acknowledge is that while yes, big Wall Street investors do largely set the tone and tenor of the housing market, the vast, vast majority of homes are owned by small time "mom and pop" landlords.
And the majority of existing home sales are Boomers selling homes to other Boomers.
They did this to themselves (and to everyone else), and the result will be that they impoverished their children while chastising them for being poor, enriched faceless corporations while claiming they hate them, destroyed the climate while claiming climate change isn't real... all while claiming that everyone else is entitled, poorly informed about how the world works, and financially irresponsible.
