Depends on geography of course, but it's not rare at all for boomers to have this many houses as a normal part of how they experienced middle-class life. As a group they are not only more likely to have rental/investment property, but also more likely to have multiple such properties. Why would they sell? They can get you to pay for all their services, and vote as a block to deny and remove services elsewhere.

Because that cannot continue in perpetuity. The cracks are already starting to show. If I were in my 60s faced with the real possibility of living another 15-30 years I'd want the younger people to feel like they had something to look forward to. Many young and middle-aged people in the US don't feel that way. What they can't get through the ballot box, they'll get other ways, ways that will cause others to say "I'm not saying I agree, I'm saying I understand."

It's the job of government to make sure that doesn't happen, not cater to it.
