Karl Marx was against capitalism that favored business, production and trading across the border. He was a believer of communism and hence wanted to restrict the business boundaries. He also said that capitalism promoted materialism due to which our present history is like this. If instead of materialism our history would have been based on ideas then it would have been way different than what it is now.
