How much is enough? How much is too little?

Below is a link to an interesting article putting our current living standards into perspective. Most interesting is his assertion that most people think of spending levels of more than three times greater than their own to be excessive, and they think that living on an income of less than one-third of theirs as being impossible.

Personally, I can easily imagine surviving quite reasonably and more or less contentedly on quite a bit less than one third of our current income, not that I would like it. On the other side of the coin I can easily imagine spending ten or twenty times our current income without having any problems with thinking of it as excessive.
