Consider a job at a university. It can be hard to get in if you don't know somebody, but that's true anywhere. Many university jobs are given to friends/family even though they are ostensibly/legally posted publicly.

You'll find many more older people there. There is politics, as there is anywhere, and the technology tends to be more boring and proven vs. new and exciting, but sometimes it's cutting-edge if you can find a research-related position. Salary won't be great, but benefits and PTO generally excellent, and it's almost unheard of to get fired or laid off, and work hours will be "normal." You can take some amount of classes for free or cheap, and use all the campus amenities.
