Capitalism and Technology - Volume 1 of Capital

In Volume 1 of Capital, Marx deconstructs the utopian vision of free market capitalism. As items become cheaper and cheaper and cheaper, then you can reduce the value of labor power even though people are getting the same number of items. This is one of the reasons technological innovation is so favorite. In fact you can even get a situation where the material standard of living of the labor can increase at the same time as their share in value production is going down. That's what a warm-out economy is about - we've seen that for 30-40 years.
