Why do you say that?

No single approach results in the 'best' decisions, and I'm not sure what the "global economy" and the "United States' represents in this case - both are very large collections of various people and interests.

The U.S. does have a very strong emphasis on freedom, you know, and has done very well with the free market and free trade - no country, in aggregate, has gotten richer following any system in the history of the world. Truly.

I'm open to improvements that distribute benefits better, but what do you suggest would work better?

It makes the best immediate decisions for immediate participants in it, which does not guarantee arrival at a global, or even local maximum.
