Another issue with increased pressurization is increased humidity. Humidity is really bad for aluminum aircraft, and definitely not good for all the electronics/wiring in composite aircraft. (airplanes get parked in deserts for a reason).

Average elevations by country...
USA: 2,500'
China: 6,000'
India: 525'
Russia: 2,000'
South Africa: 3,400'
Indonesia: 1,200'
Brazil: 1,000'
Pakistan: 3,000'
Nigeria: 1,200'
Mexico: 3,600'
Japan: 1,400'
Phillipines: 1,400'
Ethiopia: 4,300'
That's over 58% of the world population by country living at an average of 2,400 as established by word population by country, and average elevation of those countries.
I didn't try to say anything. I said it.
Just because the average elevation of a country is a certain figure, that doesn't mean all the people, or even the majority of the people live at that figure or higher... The most populated areas of many of those countries are sea level cities in coastal areas.
