The main problem -- the only real problem -- is capitalism.

It causes economic inequality.

And it does a bad job of balancing the economy.

Without capitalism, the working class will do the best possible job of balancing production and use. Without markets. Without money. Prices provide a trailing indicator of overproduction or underproduction. The invisible hand of the market has Parkinsons.

All of capitalist economic theory is bogus. We will do better after it is discarded.
