I think it is that the culture is changing with the economy... More people are making less money, yet real inflation on food, energy, transportation, and everything except technology is rising much faster than wages...which for many folks is or has declined...
With the stock market crashing and being as unstable as it has been... the housing market crashing... The fact that our daily cost of providing, food, shelter, clothing, health insurance for our families has caused a need to cut somewhere...
I know folks who have been displaced, have found new jobs making 20-30% less and having to commute 90 minutes because they are underwater on a house that they wish they could sell...
A lot of folks don't plan... They exist in the moment... and right now after all the effects of the economy, most folks are scared...
I can say that the change is not one most folks would choose themselves, but one that is out of necessity...
