I don't know how this economist comes to this figure and their methods of Analysis. Per capita income of Rs.40,000 per year means approx. Rs.3,333 per month. Do you feel our farmers, labourers, Drivers, daily wagers or let say 60% of the population earns this every month ?? This is not a real picture as when such calculations are made the average will always inclined more towards 5% of very high income people like top ranked Business families.
