Have we had any examples of capitalism that didn't produce corruption? I feel like once again you're using different standards for evidence for the two systems. We see the awful effects of communism each and every time and we correctly attribute it to communism. But suddenly there's a need for negative proof with capitalism. We can't be sure because we haven't seen every single permutation where it might be possible. But this systemic corruption exist in each real instance so far. But we don't know if it's strictly "inevitable." Do you see how that is bad reasoning? Do you see how that isn't falsifiable? It also stands to reason that this is inherent in capitalism. If you have complete freedom to purchase anything in the market, can you not see a situation where, without outside control, a successful party will have the opportunity to use capital to seize the system itself and change it to suit their needs above others? It stops being lassis-faire at that point. What about capitalism is meant to prevent that from happening? There's no inherent safeguard to keep it from developing that problem. If you want a good system, you have to look at it honestly. You can't be in denial and keep giving it a benefit of a doubt just to protect the system instead of the people living within it. The system exists for a purpose, not of its own merit. It needs modification in the same way that all systems need modification. Any creation of humankind can be improved, and one of the advantages of our kind is that we have reason and agency to continually improve. The danger lies in ossifying and exalting a system as flawless the way we do with capitalism.
