This is a problem. The key is to remember two things:
- Keynesianism is a theory of macroeconomics. You can be a Keynesian and totally believe in things like the law of demand and comparative advantage and free trade and all that, while having a different view of the macroeconomy. (Whether it's all consistent is a different question.)
- Keynesian is not a synonym for "statist" or "not Austrian." There are other non-Austrian schools of thought and not everyone who thinks government shoudl be more activist is a Keynesian. The latter is linked to number 1 above: thinking, for example, that we need more environmental regulation does not make one a Keynesian.
