What is your opinion about Communism?

[Anomalocaris]

Capital markets have emphatically -not- maximized the productive capacity of the land.  It;s important to recognize that efficiency of capital return is not always interchangeable with efficiency of resource allocation or consumption.

No, but productive capacity of the land is a trivial portion if the total productivity of an advanced economy.  But however many problems it exhibited in hindsight, Capital markets have done far better than any system of central planning in allocating the bulk of capital resource and maximizing the productive potentsdvsnce developed advanced industrial or post industrial economy.

To put it bluntly, communistic central planning is pretty good at forcing a laggard economy into catching up by overwhelming objections to adopting many of the methods and techniques already pioneered and proven by more advanced economy.  

But it is even more ineffective at feeling it's way forward than capitslusm when it is roughly level with advanced capitalistic economies, and both systems needs to find their way forward without the benefit of hindsight.
