third world peoples are better off largely because they are burning coal and destroying forests and beautiful wildlife to make more space for their cities and even distribution would result in a drastic drop in our (the civilised countries) quality of life. for example right now i get to eat meat every day, should i agree to eat it only once a week so that 5 billion africans who didn't need to be born can also eat it once a week instead of never? i don't think so.

the third world population has been expanding rapidly and will peak at about 9 billion as you say, the current population of nigeria was same as the population of the whole of africa when my mother was born. the 7 billion people we have now can barely be sustained at current levels of resource consumption let alone 9 billion who are all going to demand electricity, air travel, protein rich diets and whatnot, and will probably engage in revolutions and terrorism to get them. something has to give.

either we reduce the third world population with contraception and sterilisation,  be it forced or connected to international aid, or we agree to have marxism, impoverish ourselves and redistribute most of what we have to poor countries on the basis of to each according to his need. how disgraceful it is that our civilisation produces so many pussies who care more about niggers who aren't born yet than defending there own interests.
