This is cross my mind while i try to figure it out some of my work. I will not says anything about method of finding data nor solution.
Put it this why,
OPEC country produce around 80% of world oil,
USA produce carbon dioxide around 70% of the world although their population is only 5% of the world which is 6billion people.
In Indonesia, rich people that put their money as a "prioritas" around 0,4person but their money is 60% of the bank total account.
We can say that when we think qualitatively the feeling of rich of something (whatever) is always across our mind right ? or wrong ?
of well just another daydreaming after office time.. !!
Sleep tight heavy work to come...
