The Economic History of India
Englishmen can look back on their work in India, if not with unalloyed satisfaction, at least with some legitimate pride. They have conferred on the people of India what is the greatest human blessing — Peace. They have introduced Western Education, bringing an ancient and civilised nation in touch with modern thought, modern sciences, modern institutions and life. They have built up an Administration which, though it requires reform with the progress of the times, is yet strong and efficacious. They have framed wise laws, and have established Courts of Justice, the purity of which is as absolute as in any country on the face of the earth. These are results which no honest critic of British work in India regards without high admiration...Romesh Chunder Dutt

Two particular crimes were central to the economic damage inflicted - the land tax and the repression of domestic industry in favor of British production. He notes that in most cases, the British did not increase the land tax rate (compared to their Mughal predecessors) but they collected it more efficiently, effectively increasing the rates.
Of course modern critics are not likely to give the English as much credit as Dutt did.
