I'm 32 and have no savings (let alone retirement or college savings for kids). My car has 199K miles on it, and I can't afford to buy one that's any better. Everyone else of the same generation in my family (siblings, in-laws, cousins) have all bought houses and started families years ago. A guy from my high school class didn't go to college, became a plumber, and makes more than I do as a post-doc (and has been for the last 10 years). So he owns a house, and has already paid off a good chunk of the mortgage.
If someone told me when I started grad school that it would be a 10+ year investment with an 80%+ chance of zero return, I would have run the other way. Any sane person would. But nobody laid out the facts for me. These days I make sure to give my honest opinion to undergrads who ask me for advice about grad school.
With that said, I have one bit of trivia, and one bit of advice to contribute:
1) This year, I got and accepted a tenure track job offer at a decent R2. Last year I didn't even get an interview. So things can turn around. But more importantly,
2) Things might not turn around. You might not get an academic job, or it might require you to play this stupid game for another 10 years. If playing this game isn't fun for you, then start applying for jobs outside of academia. I had decided that this is the last year I would apply for academic jobs. Give yourself a deadline like that (maybe it's 5 years for you, you have to make that decision). And the really important point here is that I'm NOT telling you to give up on your dreams. I'm telling you to possibly give up on the idea that the only measure of success IS getting a TT job. So let me say that even though I got a job offer, I don't think there is anything magical about the place I am going to work. I honestly think I could be just as happy in a government or corporate research setting (maybe happier? I don't know). And in a couple years I may decide that. In the real world, people change jobs, or pursue a different career ALL THE TIME, and it's no big deal. But somehow we academics get stuck in this inbred mindset where nothing else matters.
So I don't think "hang in there" is necessarily the best advice, on its own. But taking a broader perspective about the path you're on is always a good idea. And "Good luck!" never hurts.
