Query: Dead wrong!!!!!

Reading this book really shows that Marx understood nothing about economy: Prices cannot be fixed objectively according to some cost computation, but depend on how much people want things, of the balance of want and demand. I recommend instead reading book by insightful persons, like Ludwig von Mises, Friedrich Hayek, Israel Kirzner, etc. Anyway reading Marx explains why all goes wrong in socialist/communist countries, why people become so poor and have so little freedom and rights. The only value of this book may be to take what Marx thinks is good as on the contrary the way things should never been done.
