Here is a fact that is absolutely vital to your material standard of living and that of your children:
Money is political.
It is a political weapon employed by one class in society to subjugate the other class and force it to labor ceaselessly.
Yet, today, we have a bunch of useless labor theorists running around who approach money as if it is above classes. There are two classes in society and, therefore, two antagonistic and incompatible expressions of the socially necessary labor time of society. This cannot but give rise to two fundamentally incompatible money forms. The struggle in society over which money form will be established as the universal equivalent cannot be divorced from the struggle over what constitutes the socially necessary labor time of the working class.
