Do you think these regions will have raised their living standards, raised their wages, and lowered their rates of political corruption by mid-century? Or will they still be relatively unpleasant places to live?
I think India will pull through in improving itself. With a population that will surpass China's by 2030, it better. Technological advances are making gains from what I've heard. Pakistan and Bangladesh will need to cool it on birth rates since both are already very dense. But Bangladeshi people have lots of kids for cultural reasons, so I don't know how they're gonna deal with their out of control population growth rate...Maybe emigration to other countries. That's what many men do in that country; they go out to the US or the UK to a good college and get a good career and then use the money to support their families back home.
I think Thailand has the biggest shot at improvement. It has large expatriate communities that could possibly aid in its economic development.
As for Africa, sub-Saharan countries have a long way to go. They would have to overthrow their corrupt governments, set up an economic system that benefits them most, acquire clean drinking water and adequate amounts of food, crack down on AIDS and malaria, and vastly improve their education systems. Borders need to be redrawn so historically oppressed ethnic and religious groups aren't living in the same country, but then again, said groups could just be invaded. Europeans drew the borders of African countries during colonialism based on oil and other resources without thinking about ethnic and religious tensions. Africa will need the help of the outside world for mass improvement.
As for the Middle East, I'm afraid that their tendency to stay living in 700 AD won't be going away anytime soon. Women have no human rights in these countries and it looks like the men in power and in public mostly want to keep it that way. Women can't even drive in Saudi Arabia. Pretty sad. I think it's safe to say that these guys take their religion more to the extreme than any bible thumper in the good 'ole South. Human rights have a long road in this part of the world.
