The realization that I came to is that each citizen for himself or herself understands the economics, which is, "I better make more than I spend and I better put something aside for a rainy day, and I want to get a good idea about what to do with the surplus so that perhaps it can grow while I'm sleeping." And that that's capitalism. Everybody practices it, but half of the country - those on the left - deny that it's true.
