Ever heard of opportunity cost?

I must admit I've not heard that phrase. Explain please.

Yes, Mags, do explain the concept of "opportunity cost"
and after that, please expound on "utility theory" and then
wrap things up with "Schumpeterian profits."

For an encore, dazzle us with an analogousness of "Gresham's
Law" as applicable to rao.
