China and free market mumbling to avoid a simple accountability comparison? Come on. Your just flailing about to keep some neat image of Capitalism intact at this point.
The only thing this had to do with is what incentive structure each set up and what the expected outcomes of those are.
Leninism:
Concentrate the power into professional revolutionaries, a vanguard, to lead the people into making the "correct" choices.
Incentive: Keep this new and unprecedented amount of power indefinitely.
Outcome: Corruption of whatever ideals they might have had.
Capitalism:
Concentrate the wealth and thus power into businessmen/corporations with the purpose of keep accumulating wealth indefinitely.
Incentive: Use the power and influence of wealth to do just that, accumulate more wealth.
Outcome: Manipulation of rules, regulations, and the market.
This is what they are. This is what we've seen for more than a 100 years for both. This is what they are accountable for.
