Depends on what stage of life you're in. Ramen profitable works for a 20-something just out of college. It does not work for a married middle-aged person potentially with kids.
It's a lot harder to start a startup once you get to that stage of life because of this and other reasons.
Those 20 somethings as potential founders was what other investment companies overlooked and partly made YC new and different. That was one of their innovations. Before YC investment companies were always looking at uni professors and execs dropping out of corporations.
Changing this focus -- to focus on older more experienced invidividuals is changing YC imo. Less social justice more hackery/building stuff people might like would be a positive move for YC and the audience. I don't think we're in such a climate to discuss this though.
Is making it easier for a middle-aged person to start a startup something that YC has to care about? There could be a separate organization that focused on that.
