I mean macroeconomic theory, most of, much of it, I could believe it, but not all of it. And later on I had to write a paper on macroeconomics for the journal that I edited for the U.N., the U.N. Journal for Development Planning. Jean-Paul Fitoussi whom I had commissioned, who was the secretary general of the International Economic Association, and a big professor in France had promised to write it, he didn't, he failed, so I had to write a chapter on macroeconomics and I realized that it had been, you know again, these, these academic economists, and many of them mercenary economists like, what's his name, Stanley Fisher. His textbook says something and he recommends something quite different when he is chief economist of the IMF. These people are really intellectual dishonest I would say.
