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

The following are the two-fold motives behind the systematic deindustrialisation affected by the British:

1.  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 flourishing industrial base.  

2. Making India a Market for Finished Goods: Another important objective of the British government was to use India as a virgin market to sell the finished goods produced by the British industries.
