alt Hacker News> Markets are the expression of an unfree society because they concentrate power in the hands of the few.
The idea of markets is that both sides are unable to influence the price. What you describe is a problem, but it isn't a healthy/free/working market anymore. I agree that the current economy is suboptimal, but the problem isn't capitalism and and free markets. It's rather a lack of the latter.
I guess see a “free market” as a contradiction, a utopia that even if it existed for a moment would promptly undo itself. As for capitalism - capture of the state by monied interests has always been a central feature.
