Well maybe macro *is* in a scientific state, from your description. Sticking to Kuhn's terminology, "normal" scientific activity occurs when scientists use existing models to solve outstanding issues. From one perspective, maco is organized around general equilibria, and the fighting is over the details of money, capital and labor markets, as you describe. The situation is similar in many branches of physics - people often accept very broad ideas (Newton's mechanics) and then squabble over details, which may seem huge to insiders, but small to outsiders.
Also: I've never bought the whole social science is too complex argument for why economics and physical science differ. A lot of the life and physical sciences deal with complex systems - ever study turbulence theory? It's prettty friggin' hard and complex. Or ecology - lot's of interrelated parts. But we still consider them sciences. Fabio > in macro-economics.
