I would argue the opposite.

Grow up with a safety net and you don't take it seriously.

Group poor and/or with people depending on you, you understand the task at hand.

I goofed off a lot in college until I was tired of partying and realized I was going nowhere; about end of Sophomore year. All the older folks who paid their own way sure took it seriously. For reference, I'm also GenX.

I'm sure motivations range from what I suggested to what you suggested.
