A focus on 'greed' or 'honesty' is missing the mark on what I'm saying here. We currently have an economy built on a foundation of historical expropriation, enclosure, colonialism, subsidy, regulatory capture, rent-seeking, etc, and heavily biased towards the resultant monopolies/oligopolies. As a consequence, prices are set at this inflated level of profit, and those who perform labor outside of the interests of these corporations typically aren't able to afford the costs of living (especially without breaking the law). "Greed" isn't really the issue here; the issue is systemic privilege born through violence.
>History has shown me that it doesn't matter what economic and political system is instituted
It's pretty intuitive that a political system is generally going to be favorable towards those who instituted it, outside of happenstance benevolence from a political elite.
