Startling "mask off" moment by the editors of history and technology. It seems to read as if what constitutes acceptable historical method is dictated by politics.

It is crazy how many TV shows and Movies retread the same historical ground. How many more times do we need to see Henry VIII and Ann Boleyn? There are so many other interesting historical stories? (IMBD has 48 items tagged with Henry! () )

The History of Capitalism it seems is not the history of economies & societies under capitalism but the history of the idea of capitalism, largely as seen through its critics. A useful clarification.

A while back it was fashionable on this website to attack Econ 101 - it lacks nuance, makes strong assumptions etc. etc. But think how much easier it would be to make the world better if legislators and voters understood just a fraction of elementary econ.

At the very least, it is very hard to see classical liberalism as the driving force behind colonialism (greed and ambition are pretty much sufficient) and very easy to imagine a much more brutal imperialism absent the influence of classical liberalism.
