Funnily enough, in my eyes it's obvious that capitalism in a globalized world must inevitably lead to unfettered capitalism, since the gravity effect of money along with competition between countries for their investments (with tax breaks etc. ) inevitably allows the capitalists to change the laws in their favor more and more. So I would ask for an objective measure of "how much in control humans are". I don't think it's a single dimension like you're implying, and I don't think capitalism is near any optimum due to the aforementioned effect.
