Talking about average is again big problem. Because by average measure US GDP is growing, education/healthcare infrastructure is getting better. But the benefits of it are only accruing to top 10% or so.

I see in India income gains are only for top 5-10% of population but those beneficiaries have caused heavy air pollution, traffic woes with their cars, ACs etc. Excessive water shortages and increasing travel times and so on which has caused much more suffering to poor in comparison to benefits which were hogged by IT/ITES and other few sectors.
