Karl Marx had many ideas as a German economist. He was a thinker of money ad was a believer in socialism. His idea was that the proletariat (the workers of factories and industries) would over throw the bourgeoisie (the rich; the owner of the business). Soon enough they would then revert to socialism. Karl Marx saw this as a natural evolution and this would become the new class system. "Society will not stop at capitalism but continue evolving." - Karl Marx.
