Who will be in the top 30+ nations as per their PPP

By the evaluation of PwC this is what it is forecasting who will be in the top 30 nations:

I have two counter-forecasts. 

Indonesia will NOT be in the top 30+ nations list as its inherent modus vivendi and operandi has always been and is by corruption.

India will be in the top 10 but not in the second spot. It will not because its operational format is too fractured; and its components wield power to assure its sub-component welfare, NOT that of India as a whole.
