In the words of Leo Tolstoy

Money has in our time completely lost that desirable significance as a representative of labour; such a significance it has only exceptionally, for as a general rule it has become a right or a possibility for exploiting the labour of others.

The dissemination of money, or credit, and of all kinds of monetary tokens more and more confirms this meaning of money.  Money is the possibility or the right to exploit the labours of others.  Money is a new form of slavery, which differs form the old only in being impersonal, and in freeing people from all the human relations of the slave.

Think about it...
