Is it possible for all countries to be developed? Why or why not?
Yes. It is easy to do with just a low birth rate. Nearly every country in the whole world considered "modern" has a low birth rate below the level of replacement and almost every country considered undeveloped has a high birth rate above the level of replacement. Obviously, developing, feeding and educating a population with fewer people and slower growth is automatically easier than with a lot of people and rapid growth.
Poverty will end in virtually every country with a low birth for a couple of decades or so. It looks like the birth rate is dropping worldwide and hopefully almost every country in the world will have little or no poverty if anybody found an successful plan or method or reduce birth rates we could very easily end poverty worldwide. I think encouraging social isolation is a good strategy for lowering birth rates and a good way to do this seems to be to encourage the use of the internet and social media.
It seems like when you have people watching movies, playing video games, and using social media a lot it causes the birth rate to drop significantly due to social alienation caused. Since the year 2010 the US has seen a dramatic decline in the birth rate and Facebook has become famous as in 2007. But the negative side of a very low birth rate is that it is also causing a population to die out. Many European and East Asian countries are now dealing with population decline issues as their birth rates are so low if their birth rates don't rise substantially in the future they'll just go extinct sometime.
A low birth rate causes the younger group to represent proportionally smaller sample sizes resulting in smaller classroom sizes and smaller sample sizes, which in turn leads to higher average scores being automatically easier to obtain than in causation not mere correlation. A low birth rate often causes a higher median age and as younger people commit proportionally the most crime it causes the inevitable presence of proportionally less younger people meaning we should anticipate less crime this again is causation rather than pure correlation.
