Full Idea
Marx gives a first-rate account of the mechanism of capitalist oppression; but so good is it that one finds it hard to visualise how this mechanism could cease to function. …The exploitation is the competitive need to expand as rapidly as possible.
Gist of Idea
Marx showed that capitalist oppression, because of competition, is unstoppable
