I think people overconsumed because they could. Loose lending, big business that was happy to let and encourage people to get in over their heads – look at how the whole credit card industry works, or doesn’t.
Overall, people should be able to exercise control. But, we don’t educate our citizens to show restraint. I think overconsumption is deeply engrained in our culture.
My parents were “Depression era” folks and that rubbed off on their kids. Maybe you have to experience it directly or vicariously through your mentors to get it.
Just too bad that we can’t have any confidence in our elected officials or business leaders.
But maybe we can teach our kids these values. Or, maybe they will learn directy for themselves.
