The existence of an "Anglosphere"

An individual named James C. Bennett has apparently written a book titled The Anglosphere Challenge, the thesis of which has been described as follows:

"the peculiar island history of England produced a set of institutions that other advanced nations in Europe and Asia lacked--the common law, respect for private property, continuous representative government, a culture that nurtures civil society and entrepreneurial enterprise. It is thus no accident that the Anglosphere has excelled in innovation and economic growth and, Bennett believes, will continue to do so."

I haven't read the book yet, but I agree with the thesis based on what I know about the subject.
