Under private property […] every person speculates on creating a new need in another, so as to drive him to fresh sacrifice, to place him in a new dependence and to seduce him into a new mode of enjoyment and therefore economic ruin. Each tries to establish over the other an alien power, so as thereby to find satisfaction of his own selfish need. The increase in the quantity of objects is therefore accompanied by an extension of the realm of the alien powers to which man is subjected, and every new product represents a new potentiality of mutual swindling and mutual plundering. Man becomes ever poorer as man, his need for money becomes ever greater if he wants to master the hostile power. The power of his money declines in inverse proportion to the increase in the volume of production: that is, his neediness grows as the power of money increases.
