Yup. Marx borrowed a lot. Very little of Marx's ideas on their own are original. Really what he did was stitch together work from multiple sources. Lots of his contradictions of capitalism come from Adam Smith in some form. Marx is also, if I remember correctly, influence by early christian communes. As I said, most of his ideas taken individually are not original to him, it is only when it is all combined, it is original.
