Westerners prefer to have only one to three children because it is expensive to have a child in North America..considering the cost of living expenses, taxes, clothes, extra food, possibly college tuition in the future..
I think its because in most cases in their lives they are busy. They are also highly educated such that they understand the burden of having many children with limited resources. Moreover they also invest too much time in school especially if you compare them with developing countries who in most cases have low level of literacy and high level of unemployment...
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
