Just because they're anecdotal observations doesn't make them wrong. Actually, if we observed more than we listened to economists, we might get further ahead.
I've already stated that I understand and have sympathy for the financial constraints Boomers are under and how that is contributing to this crisis. But I'll admit to having varying degrees of sympathy. If you are a Boomer who can't leave your large, paid-off house, it means you spent a lot of your life in the larger house you wanted, you live in a house now, AND you own a large asset. There are plenty of younger non-rich people who aren't living in the house they want now, won't ever be able to afford ANY house, and will spend all their money on rent and never own a similar asset.
Unfortunately there's no way to talk about this without all of us just starting to fight with one another about who has it worse, and that's just what the ruling landlord class wants.
Totally agreed that people with too much money buying multiple houses, in any age group, to use for themselves or simply as investments, are also the problem.
