Capitalism is as man made as theory of evolution. It's been discovered. Or it's just the way the societies always worked. Most efficient. Capitalism as an ideology is just noting the fact. Not inventing, just realization of how brutally nature is and how brutally it works. Socialism is invention from the realization that capitalism is morally bad. It's exactly like vegetarians agenda: killing animals is morally wrong. Yeah, but you know what we still need to eat. It's the same way with socialism: exploiting people is morally bad. Yeah, but you know the work still needs to be done.
>Capitalism is a recent invention. Societies in the past were not capitalistic, I challenge you to find one.
They all were. Not in social sense, but in the economic one. The challenge makes no sense. What is capitalism? As long as you let the markets work and don't interfere with people decisions on the market on a permanent basis this is capitalism. As you let the capital flow and accumulate. Once you impose restrictions to it based on ideology based in distrust to free economy or marktes, you don't have true capitalism. I.e. in communism private property is banned. Actually in some instances communists were propagating the idea of moneyless society. You haven't had such an assault on the idea of making money before socialism was invented. The first person who traded results of their labor for results of labor of someone else was a capitalist. And that's how it has always worked. Actually, even imposing penalties on people for doing trade, owning property, etc. as was common in communistic states, didn't change people's behavior who still wanted to enrich themselves. Meaning we are capitalists by design, it's as natural as eating meat. Might be inconvenient morally, but the facts are facts. Smith merely discovered/noticed the phenomenon and gave it a name. So not soon later it could have been and was attacked, but as long as our DNA doesn't change we are and will be capitalistic beings.
