Actually, the USA is both now. Large budget deficits with highly interventionist Fed monetary policy. Beyond that though - what Zero Hedge refers to are those of the central planning mentality. That government or its related organs can manipulate people and the economy to perform how it feels necessary. Some do it through fiscal policy, others try to do it through monetary policy. Either way, the attitude is the same.
