Ultimately a lot of people are going to have pain in the 21st century. Oil is a finite resource. Once peak oil becomes a reality for everyone the populations of the world will come down drastically. Maybe China will be number 1. That is if there is enough oil to support their billion plus population. Of course then there is India with a population that's just as big. They all won't be able to live high on the hog like Americans did in the 20th century. There is not enough easily available oil for that. Period!
