We better start with you and your family then. I'm surprised that trailer park you are posting from has internet.
Actually, my family are high IQ, completely law-abiding, live in nice communities, and have limited themselves to a reasonable number of children for generations.
Both my sets of grandparents had three children each, and those children were part of the baby boomer generation. Both sets of grandparents and their children lived on farms and were self-sufficient. This was before all the crazy farm subsidies there are now. If there were any at that time, they were minimal. Living on prosperous farms with large farm houses and a need for the labor, they certainly could have gone overboard and had many more than three children.
My parents and their siblings have all had either two children, three children (in one case) or zero children.
No one in my family from my generation has had children before the age of thirty or before having a stable situation to raise them in.
We are not part of the problem.
And those on these forums who are saying they won't have children are doing more harm than good. With very few exceptions, the members of this board (whether I agree with them or like them or not) are high IQ, productive members of society. It isn't just an issue of quantity, it is an issue of quality and everyone here should have children if they haven't.
