If poverty is the reason certain ethnicities have so many children, explain this!

Many countries in eastern europe have declining populations because of all the unemployment. Many people feel they simply cannot afford to have children.

Population decline is especially apparent in Romania.

So why is it all these other ethnicities are having so many babies? How are they different from eastern europeans?

I have no doubt there is a correlation between poverty and high fertility, but I think it is high fertility that is the cause of poverty, not the other way around! http://www.africanews.com/site/Malawi_High_fertility_rate_fuelling_poverty/list_messages/41471

 

I believe that this is another manifestation of selfishness. I recall watching a PBS documentary filmed in India many years ago and the producer asked a father why he had so many children. His response was that having more children provided a statistical advantage for him (i.e. the probability was higher that one of the kids would become successful and provide for him in his old age). This is a disease. We are the equivalent of bacteria on a kitchen sink. Populate until the available resources limit us.
