The definition of wealth is “an abundance of valuable possessions or money”, “the state of being rich; material prosperity”, “plentiful supplies of a particular resource”, “a plentiful supply of a particular desirable thing” and “well-being; prosperity”. Some of the definitions obviously refer to money and income, but there are many desirable things that have nothing to do with money. And from some of the definitions of the word, it appears that if you have these desirable things, you have wealth.
