The younger-than-Boomers (ytBs…is that an actual acronym?) have something they can do about investors buying properties. If you control the estate of Boomers who owned residential property, sell the house(s) to people who will
reside there, not use it as rentals or as an “investment”. Might get less money upfront, but you will sleep better at night.
Another thing ytBs (looks ugly, might not use) could do is develop aging-in-place tech to make it unnecessary to rent that second house. Aging-in-place is already much cheaper than nursing homes

What new tech would allow the elderly to age-in-place more efficiently? The elderly are too old to develop it themselves…
