>> Wouldn't it be so much easier if there were something cleaner and simpler that would make all the problems and uncertainty go away. "Simple" at what level? The principles underlying evolution are fairly simple, but have resulted in the astounding richness of the biosphere. What is taxed, punished, or regulated you will tend to get less of. What is profitable or encouraged you will tend to get more of. You can't understand all of the world from that, but you can understand a lot of it. I don't claim to be an expert on macroeconomics. I do claim to be an "expert" on that principle.
