PPP does not automatically account for all relevant sources of inflation. From your own link:
There are lots of concerns into which inflation for commodities can be determined. GDP PPP tries its best to pick a reasonable basket of goods to get a picture of purchasing power of individuals.
Like IQ testing, you're reducing an extremely complex and somewhat subjective set of characteristics into a single uniform metric. Its always going to be lossy.
But GDP PPP is pretty much the gold standard of economic wellbeing for the people.
Yeah you can look at the very contrived and extremely complex quality of life index, but it risks getting weighted by political biases.
Fact is, Soviet defectors in the 90s were aghast at the wealth of America compared to the meager existing under communist russia, just seeing supermarket shelves stocked with food was unbelievable. You can't compare that to modern day Russians living in a developed nation.
