In modern America, there are more than enough opportunities for people to get out if they're trying hard enough to do it.
or they're working against that "goal". I put that in quotes mostly because I don't think most care any more.
Regardless, instant gratification trumps frugality more often than not, which is why we're all in this current mess.
There was a TB dad quote thread and the one that stuck with me was a guy whose dad was talking about his brother and said, "he couldn't finance a Coke."
