I think there is also an increasing sense that young people should enjoy life and freedom. Travel, go on adventures etc. I certainly had that attitude in my 20s

I think there is also an increasing sense that young people should enjoy life and freedom. Travel, go on adventures etc. I certainly had that attitude in my 20s, and didn't want to be tied down. Seems like it's a relatively recent thing. Older generations had a pretty straight path from school to work to family + kids.
