I agree. The "rat race" is a competition with other humans. "Keeping up with the Joneses".

For every person saying "I'll not fly" or "I'll buy an efficient car" there are many more who'll be happy to take their spot on the plane or buy the 2000+kg SUV gas guzzler.

The only way to properly shape things is to change the rules of the game.

"Tragedy of the commons" only workaround thus far is a central body to limit individuals in the interests for all.
