One has to be even more privileged to spend time on open source work than to hold a well-paid IT job; there are additional barriers.

For instance, open source contributors need free time, which is usually a consequence of relatively short working hours (i.e. being highly competent and educated) and short commutes (i.e. an expensive house in a convenient location), and not having to spend a lot of time, when at home, on housekeeping, children, old and ill family members, hostile environment, distractions, etc.
