Michael Hudson has posted the article High Finance & Investment Colonialism that includes the Geopolitical Economy Hour.

Political economists Radhika Desai and Michael Hudson explain how imperialism is a product not only of the struggle between classes but also nations, and how the framework of geopolitical economy helps us understand the international relations of the capitalist world system.

It is not until the wrap-up phase that they make the necessary point that a mixed economy is the one that works best.

Rahdika Desai kept pressing the point that planning was important to make any economy work. She never talked about the harm that too much centralized planning can cause.

I believe that the emphasis on central planning is what eventually limited the communist system of the Soviet Union.

Of the two major communist powers, I think that China was the first to understand the need for some capitalist competition to complement the central planning part of socialism. Only later, with the breakup of the Soviet Union and its brief castastrophic dalliance with USA style privatization that Russia too learned the lesson that China had learned.
