[1] I'm not making a claim of fact here, just saying that there's an intelligent debate about the issue. http://en.wikipedia.org/wiki/British_Raj#Economic_impact
and doesn't all this depend on how what you consider a country? hasn't Wales been colonized by the English for a long time or does some geographic separation have to exist?
And is colonization of Korea during ww2 less destructive than the British colonization of Hong Kong? Or does the colonizer matter?
Since you've simply flat-out contradicted a research paper with nothing more than assertion, I find it unlikely your upvotes represent anything more than a set of people who found their preconceptions tickled by your post. Do you have any sort of actual other study to back you point up, or are you just stating your own biases?
(I don't feel much like I have a horse in the "colonization is evil" fight, since I think anyone still personally offended by events from over, say, 150 years ago already has problems I can't solve. But the question of why cultures succeed and fail is one of the most pressing questions the human race faces and having it muddied up by stupid political games is costing lives.)
How do you know what the condition of India would have been under British rule?
Was there a sharp upward trend in India's gdp/growth rates/etc after Britain left? Or did the 10 post-british years have higher growth rates than the last 10 british years? I'm genuinely curious.
Using our societal mores to judge the benefit of our occupation is precisely the sort of paternalistic jingoism that makes colonialism such an unmistakable evil.
To Western eyes Indians are one race, but what Ghandi stood for was apartheid * 10.
As for what the British did in India, http://en.wikipedia.org/wiki/Sati_(practice)#British_and_oth...
Also when you look at his views closely, especially after 1925 or so, he moves into a position very similar to that which you will see of modern Christian theology, where you hear much talk of the importance of personal choice. So people should follow a caste and so on, but that's not the place of the government to enforce. That's a much more moderate and workable position than abolition, and much easier to implement. Absolutes do little good when aiming for radical societal reinvention.
Even Sati was pushed out bit by bit, by various reformers. But again, from a vegetarian Hindu perspective large-scale livestock slaughter is a similar if not worse evil than Sati, and unless you can provide a proof that animals don't have souls, your rationalism has no place in that discussion. You might as well commend the Communist party for bringing about gender equality as a counter argument to someone railing against the gulags. All it shows is that we always have some places where we cannot accept cultural relativism.
