Well, you don't have to have an insane salary to have this problem either. I had the same problem when I worked as a part-time math tutor post-college. <$15k/yr, but single, no debt, and I lived modestly. Basically the three people who could spend any time with me were two who lived basically the same lifestyle, and one who was a teacher and thus (briefly) free during summers. Nowadays, I work (and make, thankfully) much more than that. But even working startup hours, I still find that the majority of my friends have no free time. What they don't spend at the office, they spend fixing the big houses they own. Busy-ness is such a disease in today's culture; no-one gives themselves time to live, and when they do, they are forced to feel guilty about it, either implicitly or explicitly, by their co-workers or employers.
