Yep, and people who are disabled (or act as a caretaker) are in a similar boat.
Ironically, you are probably a better bet for a lot of employers than that average young single male because you value stability. You're not gonna jump ship because you want a foosball table or expect to have lunch catered every day.
Unfortunately, the market for labor is notoriously unequal and illiquid. The desire to save via a large workforce of what you're calling "averge young single male"s often looks much better on a balance sheet than a few well-paid older folks. There's lots of different kinds of capital, but SEC filings definitely favor "objective" measures like number of desks filled.
So to say that I must drive myself crazy just to meet your need for me to have OSS projects on my resume, I rather work somewhere else.
Side note: I work at a dream job, getting paid below market value, and won't trade it in because... how many people work in a job where everyone is underpaid and wants to be in the office every day because it is just so amazing?
