From McCraw’s discussion of Schumpeter’s “legacy”:
(p. 500) In the new world of academic economics, neither the Schumpeterian entrepreneur as an individual nor entrepreneurship as a phenomenon attracts much attention. For professors in economics departments at most major universities, particularly in the United States and Britain, a focus on these favorite issues of Schumpeter’s has become a quick ticket out of a job. This development arose from a self-generated isolation of academic economics from history, sociology, and the other social sciences. It represented a trend that Schumpeter himself had glimpsed and lamented but that accelerated rapidly during the two generations after his death.
