The systematic destruction of the Jewish people by the Nazi imperialist regime of the 1930s and '40s Germany by the latest technological innovations, and its documentation by modern capitalist book-keeping techniques, likewise was a direct outgrowth of a rapacious capitalist system that had a long history of visiting destruction on its own people, colonies, and workers and peasants of opposing armies in the trench warfare of World War I. A system that does what ours does to its own people, and to people around the world, can also do what the Nazis did to the Jews of Europe. That potential is part of the system, not a bizarre anomaly. To explain this, I want to go back to some of the early Marxist thinkers and organizers. It has developed the productive forces to such an extent that humanity must either pass over to socialism, or for years, nay decades, witness armed conflicts of the 'great' nations for an artificial maintenance of capitalism by means of colonies, monopolies, privileges, and all sorts of national oppression. They were right.
Profit is invested in further production.
But no national capitalist state can have a self-contained economy because natural resources are unevenly distributed around the world. Also, the consumer market for the things produced cannot absorb the total, so markets for these things must be sought outside the national boundaries. Capital investment outlets must be sought outside the national boundaries as well. Technology is the part of this cycle that has so raised the stakes of imperialist wars over previous wars. After all, all history is the history of warring social classes.
