Ignorance may or may not be bliss, but it sure is liberating. When you don't have to understand something, pissing on it is a cinch.

Capitalism persists not because it is good but because it is better than anything else. Capitalism is better than anything else because it solves a very thorny problem in economics - the optimal deployment of productive resources. Socialists' economic goals are agreeably Benthamite - the most stuff for the most people. But we cannot have the most stuff for the most people unless we actually make all that stuff, and making stuff consumes resources. So it matters what gets made, because when something is made, the resources going into it are not used to make something else.

People disagree on what stuff to make. A market economy provides a feedback loop in which the most desired products get made because the makers of the most desired products get rewarded, and the makers of unwanted products are punished. What other system achieves that level of real-time productive guidance?

We call the disparate treatment of those who make useful goods and those who make useless goods "investment risk." Capitalism is all about investment risk. Indeed, one could define capitalism as a system under which investment risk is taken by those with the power to cause goods and services to be offered. The horrible things that anti-capitalists rail about are not entailed in that definition. Those things are not features of capitalism; they are not even evidence (much less proof) that capitalism is not the best way to decide what to make. They are simply problems that capitalism does not solve. That's why we have government.

Someday, capitalism may be replaced by an algorithm that decides what should be made, by whom, for what price. But I'm thinking that's a very long way off. Or maybe it won't happen, because the only part of capitalism that needs to be retained is the investment risk that makes capitalism capitalism. The rest is details to be worked out...
