And related to these two ideas, you have industrialization, which is the use of technology to become more productive, to increase output, and they all feed off of each other. A capitalist says, how do I get a better return on my capital? Well, I should industrialize. I should make my factories more efficient. Well, to make my factories more efficient, I have to also invest in technology to get that industrialization. The more I industrialize, the better my profits, and so the more I am going to be able to invest in this cycle. As I'm trying to industrialize, I have all sorts of problems that I'm trying to solve, so it's going to drive the need to improve my technology.
