Yes, in fact I've heard people argue the opposite point, that EU benefits Germany more than the rest of the EU countries. The argument starts from Germany being more competitive than most EU countries. Protection from external trade is usually needed so that an industry can home brew and reach competitive or almost-competitive state, and trade barriers are then removed to keep improving against competition. But with competition in place you can't go from zero to one in established industries. The result, the argument goes, is that Germany ends up owning entire industries within the EU.
But some people cannot conceive that some arrangements can be win-win.
