After independence, Indians understood that unity is strength.
people resigned from their government jobs and applied for jobs in indian industries.
post independence there aroused complete democracy and decline of monarchy.
A constitution was formed which was based on the constitution of other countries and gave each n every person equal rights irrespective of caste,creed ,colour.
the indian trade , artisians ,craftsmen all flourished as people completely boycotted
English goods n favoured indian materials.
Thus the economy of india increased bcoz tax paid was used in india and not in England.
Finally india was not a source of raw materials for England and there was no drain of wealth taking place.
