Marx had plenty of problems with Germany - or specifically Prussia - too... In Critique of the Gotha Programme, for example, he harangued the now SDP for arguing for free state provided education, on the basis that he argued it was rather the Prussian state that had a severe need of being educated by the people. (He favoured a US-inspired model of public licensing, but privately run schools instead)
