Step 1: Theoretical Roots of Differential Rent:
The British classical economist David Ricardo argued that land rent is paid for the use of the “origil and indestructible powers of the soil.” As a population grows, society is forced to cultivate less fertile lands. The difference in yield between the most fertile land and this newly cultivated, less fertile land is what Ricardo called the “economic rent” (or surplus).
Step 2: State's Claim as the Ultimate Landlord:
Under Ricardian theory, if the state did not tax this economic surplus, it would go directly to the landlords. Since this surplus was created by tural fertility and population growth rather than the landlord's labor, Ricardo argued that landlords were idle rent-receivers. Therefore, the state had a right to claim this surplus in the form of land revenue to prevent a parasitic landlord class from forming.
Step 3: Impact on British Colonial Policy:
These ideas heavily influenced colonial revenue policies in India, particularly the Ryotwari system in the Bombay-Deccan. Relying on Ricardo's economic models, British officials believed that they could extract high, flexible rents directly from the cultivators (ryots). This led to over-assessment, high revenue demands, and widespread peasant poverty and debt.
