What you say makes sense and as per goldman Sachs if India grows continuosly for 6.5 % then by 2050 we will have per-capita which is 1/3 rd of US. is it possible to have 6.5 percent growth for 40 years, I think it is possible. US took a long time to reach the present situation. So also Japan, Korea etc. We can catch up. However imagine a 1.5 billion population earning 1/3rd of US Per-capita, it will be devastating on the environment. There is no way out of the conundrum, nature is going to cull a lot us. but then PPP are useful data when western companies want to outsource jobs to other countries.
