Do you honestly believe India has "equivalent wealth to Western nations"? Per capita GDP of India (granted it's been awhile since I looked at the numbers) is something in the neighbourhood of $2,000 USD. For comparison, Canada's per capita GDP is greater than $45,000 USD. Of S. Korea, Japan, China and India, only Japan approaches a similar per capital GDP as Canada. China, as large as they are, their per capita GDP is closer to India's than it is to Canada's (or the US or the UK or Sweden for that matter). Hate to break it to you, a railroad and postal system does not make a country wealthy!
Your point on "benefits" is woefully irrelevant. Think about it, if a burglar comes into your home, takes your TV, laptop, jewellery, the Monet hanging in your bathroom, etc., etc., etc. and while the burglar is making his/her getaway drops a brand new iPhone whatever ProMax in your kitchen - how relevant is the benefit of said new iPhone to you? How asinine would it be for your neighbour to walk up to you and say "I'm not disputing that getting robbed sucks, my point is you now have the benefit of inheriting a brand new iPhone whatever ProMax"? You really should've just stopped at "Clonialism was driven for the benefit of the occupying nations. Nobody disputes that" and be done with it! LOL!
