In reply to TobyA:
I made a mistake in saying you could read better than I can, apparently, as your resume of China Tibet history is inexact, and has nothing to do with the analogy you give... before reading take a look at a map of the world and try to locate China, Tibet, India, New Zealand, Britain... then read up the facts.
Concerning the Algerian middle classes: there have been quite a few studies written on the sociological aspects of the colonisation of Algeria and the way it was managed. This was done in quite a different way the the British colonization of India, for example, where a small number of Brits ruled a large area and created a local middle class to help, which in turn helped India when the country obtained its independence.
In Algeria large numbers of middle and working class French settlers made this training less necessary so a native middle class was not created, and those that had existed either were forced out or killed in the War of Independence... This lead, and still leads, to major problems after independence.
It's an error to imagine that each colonial country used the same methods, they were often quite different in many respects.
