I ran across an interesting blog post on the website of the American Enterprise Institute. It provided an introduction to an organization called Peers.org and their attempt to create a "sharing economy."
Here's the link to their video

The idea would seem to be a good one. We have an attempt to show that our "self-interest" benefits by cooperation.

I would maintain that is similar to the modern market place. You and I meet the market place to cooperate through mutual exchange and we both benefit.

My question for the class is "Does the Peers.org approach lend itself to unethical behavior through free-riders; or does it merely simplify the marketplace with a return to barter based on some level of comparative advantage instead of using money as medium of exchange?"

I hope this generates some discussion.
