Hmm, I see what you're saying, but many would argue that evolution is not particularly elegant, in fact rather crude. However let's go with your assumption anyway. I still don't think present-day capitalism works elegantly, the quite regular boom-bust cyclest are a testament of that.

It "works" because it has to, when it doesn't we do bailouts and then it "works" again etc. in other words anything works if a society is organized in such a way that it doesn't know or contemplate anything else. If you only know one style of music, that music "works" for you, because it sort of has to.

My point is, capitalism as it is today is one that even The Wealth of Nations doesn't agree with.

Now that doesn't mean every aspect of capitalism is bad etc. No, in fact when it works as intended it can indeed be quite elegant. the problem is it often doesn't work as it was envisioned. We therefore need to look at other systems, pull some positive aspects from them, tweak the current capitalist system so that it works more like it was supposed to, that's all am saying.

Some would say it works in spite of our interjections, not because of them. If we didn't bail out bad actors, they'd likely go bankrupt and the system would work around them. I'm not saying there's no pain involved. In fact, there can be quite a bit for individuals. But at the system level, there's a reason capitalism had beaten out any other competing economic system, from the industrial to the information age.
