Drain of Wealth Theory: Dadabhai Naoroji, Components of the Drain, Estimates and Impact on Indian Nationalism (UPSC Notes + PYQs)

UPSC has already asked about this. Read the story with these questions in mind.
Who said what
- Dadabhai Naoroji: “The Wants and Means of India” (1870) and later the book of 1901; estimated per capita income at ₹20 a year in 1867-68.
- R.C. Dutt: Economic History of India (1901-03), on land revenue and deindustrialisation.
- M.G. Ranade and G.V. Joshi: Indian political economy, protection for industry.
Components of the drain
- Home Charges: interest on public debt, India Office costs in London, pensions and furlough of British officers, army costs, stores bought in Britain.
- Remittances of salaries and savings by British officials.
- Profits and dividends of British investors in railways (guaranteed interest), plantations and banks.
- An “export surplus”: India exported more than it imported, and the surplus did not return as investment.
How big was it?
Estimates differ. Naoroji put the annual drain at around £12 million in the 1860s-70s; later nationalists gave higher numbers. Economist Utsa Patnaik’s 2018 estimate of colonial transfers, compounded to the present, ran into tens of trillions of dollars. The exact figure matters less than the mechanism: India’s taxes paid for British costs.
Why it mattered politically
The drain theory turned a moral grievance into an argument. It explained famines and poverty as results of policy, not fate, and became the base of the Swadeshi call to buy Indian and of the demand for Indianisation of services. The 1896 Congress session passed resolutions on the drain, and the Welby Commission (1895) heard Naoroji’s evidence.
