if you want to achieve some greater good, capitalism is not the ideal model to begin with. it creates a lot of wealth, but needs strong external forces to not only focus on profits or destroy everything in the process.
This system has no imbued morals or ethics, and the more we try to imbue some to it the more it fights back (again, the ad nauseam "less regulation" repeated over here). We need a new system that evolves this bullshit into something more humane.
It's not like the USA with its hypercapitalism, and absurdly immense wealth has achieved the greatest utopia on Earth so we kinda know capitalism is not the final answer.
