Regarding moving on to a "new Nash equilibtium," I think the challenge will be getting people to: 

. Move away from "I'll do solely what's best for me alone"
. To "I'll do what's best for me and others because ultimately that's what's best for me. "

The obstacles are 1. the first option gives the largest and IMMEDIATE "payout"; 2. the benefit to others is hard to see; 3. the benefit to me of benefiting others is hard to see and DELAYED usually; 4. people can be powerful dumb.

But, maybe there's a chance. 😀
