Communism in a minute: Karl Marx makes the assumption on page 2 of "the Capital" that if an apple costs a dollar and also a pear costs a dollar, that this is equal. So for him exist only cardinal numbers not ordinal numbers. But in real live, if I give you an apple for a dollar, I value the dollar more than the apple and vice versa. If not so, why would I go into exchange first hand? If the fault is at the beginning, it might be small, but the whole building falls down eventually.
