What was the two-fold motive behind the systematic deindustrialisation effected by the British in pre-independent India?

The following are the two-fold motives behind the systematic de-industrialisation effected by the British.
(i) Making India a Supplier of Raw Materials— The main motive of the British Government was to make India a mere supplier of cheap raw materials to feed its own rapidly expanding industrial base.
(ii) Making India a Market for Finished Goods—
Another important objective of the British Government in de-industrialising Indian economy was to use India as a large and growing market to sell the finished goods produced by the British industries, so that their industries never face a demand shortage and could keep on flourishing.
