These places merely prove the point that more people equals more wealth. In every country where the population is increasing, so is the standard of living. Some of them (such as India) are even reaching a point where a viable middle class is emerging.
Some of you don't seem to understand that wealth is not something that is to be distributed, it is something that is generated. And the thing that generates it is people. All factors being equal, more people equals more wealth. The reason these countries lack the wealth of the US is that other factors are NOT equal. Many places lack the rule of law, have deranged and oppressive government policies, lower initial capital for investments, etc.
The material standard of living has increased worldwide due to mechanized production. Not because third worlders fed on the Western dole are having more kids.

Humans aren't immune to population pressure.
