What is clear picture?
Congrats, you rediscovered PPP. Thats not inflation btw. Thats purchasing power parity.
Once again, PPP or purchasing power is not same as inflation.
When you adjust to inflation you look at what YOUR OWN income fetched in PAST vs what it fetches NOW. When you look for PPP, you compare what a certain amount of money fetches in ONE place to ANOTHER.
These are NOT same concept.
You can actually express inflation adjusted GNI/GDP in PPP dollars too.
Take a look here (its from data.worldbank.org)
1. GNI PPP (this addresses for different prices in different places)

There is GNI PPP in current internation dollars (this does not address the inflation)
There is GNI PPP in constant 2011 international dollars (This ensures that all your money is adjusted to inflation with 2011 as base).
2. GNI (this does not address for different prices)

Again there is a constant dollar version (which addresses inflation) and a current dollar version (which does not).
So you have four metrices
1. GNI in current international dollars (which is what you are trying to use and failing)
2. GNI PPP in current international dollars ( which is what you are alluding to and failing now)
3. GNI in constant international dollars of a given year. (which is what I mentioned)
4. GNI PPP in constant international dollars of a given year. (which is even better but then you will cry about PPP)
First understand then talk about it. Okay?
@Nilgiri Did you also struggle to teach these folks basics?
