As I said elsewhere it's not just poor that are obese and malnourished, it's the rich as well. 

It's not just poor that can grow lazy, the rich can too.

No amount of generating mostly useless psychological terms can cover over "habits" of doing what is easy and feels immediately good or more pleasing.

The science and practice of the virtues needs to be relearned, not just in the pooor but in the rich and everyone else in the middle. 

As I think it was Epicticus who said all moral virtue can be summed up in two words: abstain and sustain!  Our society has regressed here.
