I am thinking about this kinds of things and for years. The more time it passes the more I think it will acctually come to this in the end.
Developed and undeveloped live in different realities and the gap is growing.
On another hand when it comes to numbers it is more or less obvious that developed is clearly outnumbered.
US,Canada, entire Europe,Russia, Japan ,S. Korea, Australia , New zeland and few other small countries that could come into "fully developed" club make less then 20% of world population. (about 18%)
Not to mention that the number is droping as years go by.
Inside China there are divides between 100 mil. rich and everybody else, what creates a lot of social stress.
Also inside developed world the biggest growth belongs to the groups that have starting point in undeveloped part.
To tell you the truth I think that we will soon reach braking point when it comes to this. In many parts of the world this is already observable.
Can it be that division in WW3 will be based on amount of education and technologcal development?
OP is not big since I don't want to cut out any part(s) of this topic out.
