If the world had, to date, persisted under a poor political / economic system with only a few similarities to the ideal one, you would be able to say the same thing.

It's reasonable to imagine that there was some sort of "natural selection" of economic systems and that the one that emerged is relatively close to ideal.

The anthropic principle is relevant here.

And yes I read the rest of the article, and I don't think it recovered from this error.

I'm open to suggestions for how I might improve the introduction to the article to make the article more palatable.
