They've had decades to save up the money that allows them to do the things alongside work.

They also came up in a time and place that allowed them to build social relationships outside of work. Many Gen Xers and Millennials just... don't have that kind of personal time. I know several people in my circle of friends who don't want to do anything after work because they're exhausted. Bills gotta be paid, and there's more pressure to squeeze more productivity and consumption out of individuals than there was in 1980-1995. A lot of that pressure, oddly enough, comes from the necessity to keep shareholder returns high to keep the retirement accounts of the Boomers flush with cash.

Gen X and Millennials are also less likely to have had kids than the Boomers, so the socialization that came along with having a child (extracurriculars, PTA meetings, etc.) just never happened.

We incentivized, and eventually started requiring, economic output and consumption over building in-person social networks and hosting events outside of work. It was what we considered important.

I'm curious how you figure that pressure to increase profits has increased?
