As Marx has said:
”The philosophers have only interpreted the world in various ways—the point however is to change it.”
Learning of how present system works is of course necessary first step.
There is probably some truth in what your are saying. I found the critical research of Bichler and Nitzan be refreshing and original, especially their empirical methods.
Interestingly enough, Nitzan before becoming a professor worked for five years as Senior Editor at the BCA Emerging Markets Strategist. And their books are mostly admired not by economists, but by mathematicians and physicists, although they do not use heavy math. Your opinion about their work, as someone who works at Wall Street in quantitative analysis, would be very interesting.
