Overpopulation

Overpopulation may be a product of our own selfish interests. Humans want to have as many descendants as they can, no matter the cost. According to Dawkins however, when a country becomes overcrowded, the rate of population growth should drop because of our genes. Females drop their fertility rates when they notice lack of resources. That has been proven with science experiments. However, in the present world I see the opposite. Rich countries, where the standard of living is high, such as European countries are suffering from lack of population, to a point in which governments are having to give rewards to people who have kids. Instead, in countries like China and India, which are countries that have a lot less income per person, overpopulation is a big problem, so big that governments have to reward people who don't have any kids. It could be a cultural thing, but then you have the case of Japan, which has almost worst lack of population problems than Europe. So the real life cases apparently contradict Dawkins's theory. But then there's the cost of living in Europe and in Japan, versus the cost of living in China or India. Since in general, European countries are richer than China or India, the living cost is also way higher, as well as in Japan. Tokyo has been officially labeled as the most expensive city to live in in the whole world, and after NYC, European cities like London, Paris and Frankfurt follow. Therefore, we can see a little of selfishness there, which could explain overpopulation and relates with Dawkins's theory. Or not preciselly selfishness, but these people have no kids because its too expensive to mantain them. They will rather have a good life without kids than pass their genes, even though that goes against their own genes. But the selfishness could be seen when we talk about countries. Lack of population does bad to countries, as well as overpopulation. But people in Europe prefer to live a good life and leave the task of developing the country's population to others, while Chinese and Indians prefer to pass on their genes, and force the others not to pass them on so that the country can improve. This is an example of the selfish gene.
