I’ll try to cheer you up a little:
Owning a house: to an extent traps you in a physical location. Your job pool is smaller, and everyone you like who doesn’t own a home eventually moves away. As a bonus, the longer that pattern goes on, the older you get, and the more difficult to replace the departed becomes.
No kids: You seem pretty upset about global warming and the economy. Not having children has to be one of the single most impactful environmental choices you can make. I don’t have figures but your carbon footprint has to be a fraction of anyone with kids. Also, if systematic collapse is as inevitable and imminent as you suspect, it’s a good thing you don’t have any kid(s) for to be exploited by Tina Turner into fighting to the death in a big iron cage.
The big three.
