The single biggest problem with it is that it seems to require constant infinite growth to remain stable - feels like a house of cards, doesn't take much for it to collapse. The crashes are inevitable, and there is a human cost to them that no government should find tolerable (Tangent: governments are not businesses and a LOT or our societal ills are rooted in the misguided idea that a government should be run like one)... Anyway generally nay, capitalism and its profit motives rot society and institutions and should not exist without strong consumer protections and a strong social safety net in place
