The nature of this new mode of production is that it must be continually revolutionized. If it does not continually seek to improve its productivity, increase profits, and lower costs, it will die. Accumulate or die. This sends the bourgeoisie chasing profits all over the world and creating a world market. New wants are created.
Nations are also interdependent.
Intellectual property of individual nations becomes common property. It is harder for a narrowness of thought to exist in nations. Corresponding with this material nature is that the whole relations of society undergo great change. All that is solid melts into air, all that is holy is profaned, and man is at last compelled to face with sober senses, his real conditions of life, and his relations with his kind. The bourgeoisie arose out of feudal society.
