New methods and technology in fishing have meant that we've been (nearly quite literally) sweeping the ocean. No one disputes that we're down below 10% of large fish stocks. The question is, if we stop now, will the fish be able to get back up again to self-sustaining levels? It's unkown. But we haven't stopped fishing/sweeping. Why? Because it's not a 100%, and as long as that's the case, the fishing industry is loathe to lose its income on a mere 'speculation'.
The free market is sometimes a bright child, and other times a petulant, special-needs brat. It is often shortsighted and cliquish. John Nash discovered this and corrected it, but we still are operating in the old mode of Smith thinking. You say that a CEO is worth 200-times an average worker because the markets say so, but that's not a Nash equilibrium. You can have it for a while but it won't hold for that very reason. Extreme wealth distribution in either direction (very equal or very unequal) is not a Nash equilibrium and, until it become one, the center won't hold.
It's you, Paul, not these children/students you chide in your essay, who's operating under a poor model.
