Besides, in addition for it being illegal to discriminate candidates based on marital status, in my experience nobody that does interviews ever thinks of considering that as a hiring criteria.
I'm sure the people that perform interviews are not discriminating and I'm certain a number of bright, older, time-squeezed people make it through. But maybe I would imply conspiracy since I'd imagine the people at the upper levels, that designed the process, have at least noticed that it's biased in favor of young, recent graduates able to give extra time to the company.
Maybe you're arguing that people leave their jobs after the fact due to thinly disguised rationalizations of these proxy metrics affecting raises, but that's a huge stretch. I've seen plenty of cases of bosses and coworkers being understanding of personal circumstances (and I'd go as far as saying that is more so here in SF than at previous jobs in Canada) and I've yet to see these alleged backstabbing evil brogrammers. Saying that a company likes this or that is also anthropomorphizing something that isn't sentient and strikes me as a strawman.
