In exchange for more economic opportunity, I grew up with no family (other than mom and dad) which I think has stunted my personal growth a lot. Other people seem to care a lot about their families and getting married and having children but all of those things are really foreign to me.
Actually I'm not even sure about the economic opportunity bit; I saw loads of Romanian college students as interns at my last SV internship.
I'm not poor but I think being selfish and alone might be worse.
