Good stuff. I’ve brought up similar thoughts on this board in the past, but it seems that law schools, regardless of empirical evidence to the contrary, have textbooks stating that monopolies exist without the help of government. Therefore, let the ignorance continue under guise of “antitrust law”.
I took antitrust in law school, and believe it or not, they don't really get into that issue very much. They just drill the Sherman, Clayton, and FTC Acts and the case law into us. How monopolies happen is certainly part of the equation, but that's all determined by legal guidance that has been on the books for decades or longer. The economics angle is something Congress needed to study better when they wrote the laws, but of course, if Congress actually considered real economics when writing its laws, probably 80 percent of the laws wouldn't exist.
