"...And then maybe people start working together, and that’s a really nice effect that makes you think 'if we do all work together and all did our share, then it can work, and all it cost is that we grow a little bit slower.'"

Boom/bust, perhaps- lynx & hare, wolf & moose, hawks & mice, etc; isn't okay that were subject to the same dynamics? I guess we are in an energy boom now.
