Americans live in a culture which constantly points out to us all the stuff we don’t have. TV commercials, other people’s cars going by, store windows, everywhere we look there’s something we could potentially want, and some of it we can’t afford.
It helps to step back and take a more global view. There are plenty of people in the world working as subsistence farmers who have so little that they can’t begin to approach what Westerners call doing without.
