As I remember it, there were two grave errors in the economy of Marx. The first was the labour theory of value. Mises has shown that the value comes from the mind of individuals. But if you just look at the numbers, it seems that value is connected to price of the work and capital factors (capital being condensed labour). The explanation is that when consumer revalue some product higher, work and capital will line up behind that product. Hence the correlation is indirect, starting with consumer preferences.
The other grave error is that the profits that the capital owners reserve, is partially hoarded. Since the workers did not receive their complete productive value in wages, they would not be able to consume all the goods they produced. Therefore there will always be overproduction relative to what the consumers could buy. The funny thing is that this is exactly what Keynes and Bernanke puts forward now. They must have gotten it from Marx. Mises on the other hand teaches us that demand balances supply, and money is not in the equation. Demand being the value of the work brought to the market. The amount of money is irrelevant, and rapid changes in money holding preferences will only momentarily produce imbalances.
It would be presumptuous of me to weigh in on Marxist vs. Austrian School debate. My understanding of both is laughably shallow.
I can only point out that both Marx and Mises are currently on the fringes of mainstream economics, while Keynes' work remains canonical.
Travesty
Me neither, but moooing is sometimes nice.
