Adam Carolla – Economist?

I’ve been a little behind on my favorite podcast, but check out this (approximated) bit from the February 7 episode, where radio host, comedian, writer, etc. Adam Carolla makes his case about why he doesn’t like inefficiency. He and guest Kevin Smith sum it up thus:

When my wife and I finish a pizza and she wants to throw the rest away. She sees a pizza. I don’t see a pizza. I see a farm, and a bakery, and a delivery truck, and a pizza shop, and a pizza shop owner… Its waste! How can you possibly want to throw that away? Give it to the dog… I’ll finish it. Its a farm, and a delivery truck…

Could any economist or political scientist come up with better moral reasoning behind not wanting to throw things away needlessly?
