New research by French economists Lucas
They studied household consumption surveys, federal accounts and income tax data from 1922 - when the tax was introduced in India - to 2014.
The data shows that the share of national income accruing to the top 1% of wage earners is now at its highest level since Indians began paying income tax.
The economists say the top 1% of the earners captured less than 21% of the total income in the late 1930s, before dropping to 6% in the early 1980s and rising to 22% today. India, in fact, comes out as a country with one of the highest increase in top 1% income share concentration over the past 30 years," they say.
