You're not wrong. Overall, they may be better off on paper, notwithstanding changes in cost of living. However, relative to the upper classes, they are worse off than they would be if the upper classes hadn't gobbled up a disproportionate part of the increased wealth of the nation. Extreme poverty is still a giant problem in India and I think it's unjust that they should see their proportion of wealth decrease (by 40% since the 80s!), even if their total wealth increased somewhat.
