There is one good thing about Marx: he was not a Keynesian.
In the '30s, the Keynesian stuff worked at least in the sense that you could print money without inflation because there was all this productivity growth happening. That's not going to work today.
At the time, my personal research objectives were to provide Keynesian economics with more rigorous foundations and to tighten and elaborate the logic of macroeconomic and monetary theory.
