Wrong way to look at things. Our exchange rate based per capita income is purely based on supply and demand of the dollar within India. It's impossible for our currency to be strong when our forex reserves are low and we have a large trade deficit.
According to the UN, HDI is determined by per capita income based on PPP. And to be a developed economy, we need a per capita income of $20,000.
India is at more than $8000 and China is at more than $18000. China is very, very close to transitioning into a developed country while India is about 15 years away (at today's prices).
Purely on per capita income, this is a much more reasonable method. Note that the figures are in PPP, not exchange rate.
India is at level 2 and slowly transitioning to level 3. You can say that India will be at level 3 by 2025. Only 2% of our population is now at level 1.
China is already at the end of level 3 and on the cusp of level 4.
Purely on exchange rate basis, if India becomes a trade surplus nation with $300B or $400B surplus, and the forex starts growing by $200B a year, then why not, $14000 is extremely easy to reach if everybody is swimming in dollars because the rupee will simply strengthen by 40-50% in just a few years of reaching such amazing trade and forex figures. Logically speaking, had the UPA not mismanaged the economy, then our GDP at the old exchange rate even with muted growth would have been $4T today, which means per capita income would have been $3000 and not $2000. Are you saying we are poorer today in 2019 than we were back in 2012? You see how exchange rate based GDP is meaningless.
