> Profiting by fixing problems is how we fix problems.
I take your point. But only partly: the profit motive can be useful to some degree for some situations, provided that market failures don't undermine the connection between private action and public benefit.
(Aside: Many classes of problems are solved without an explicit profit mechanism.)
Also useful:
- rules for such mechanisms (a "floor", in a sense, for how they operate)
- expectations for such mechanisms (what we hope they accomplish)
- philosophies and moralities for people that guide us
P.S. Bonus points if you can answer this question. Mathematically speaking, what would it take for a market to incorporate the relevant time horizons and externalities such that we might have even a 50% confidence that a market would get the incentives right to reduce global warming?
