Having assigned my students a paper on Aristotle's economic thought, I was shocked to see how many of them characterized the Philosopher as "utopian" and "an idealist." I puzzled over this until I realized the cause: Any check, moral or legal, on acquisitiveness is seen by young people today as utopian! They cannot conceive that acquiring a certain amount of wealth, while often necessary to living a good life, is not sufficient; for them the good life simply is getting lots of stuff.
Markets are wonderful tools that promote allocative efficiency.

The moneychangers don't just have a booth in the temple; they are now the priests running it.
