People adapt. I've often been amazed at how little I can get by on.
I lost my job back in 2007 and have been out of work ever since. At first I was really worried about making ends meet but then I discovered that I could get by on almost a fraction of what I needed to "survive" when I was working. It actually COSTS a lot of money to work ... gas, vehicle maintenance, clothes, food, etc.
I'm ok now ... being on pension ... and it's "nice" to be able to spend money for fun again ... but people really don't really need half of what they spend, in order to survive.
Reminds me of that verse in the Bible ... "I know both how to be abased and I know how to abound ... both to abound and to suffer need."
The REAL picture emerging from a full depression will be quite different than what is presently being envisioned and projected.
