monvais, I understand you’re from an entirely different culture and history than the people you’re talking about. So am I. Here’s a thought experiment.
Imagine you live in a country without Medicare. Without Social Security. Without a bank accessible to you, which isn’t really a big deal because you make very little money. You have a few fields in which you grow food for your family, and maybe you have some spare to sell at the market once a week. You might get some money, but you might just trade your extra food for cloth, or batteries or other things you need.
Your “retirement account” is your children. Your children will care for you when you get too old to work those fields, and too tired to walk 15 miles to the market. Your children will share their food with you, make sure you have clothing and that you get to spend time with your grandchildren.
Unfortunately, you know that some of your children won’t live to be adults. Others will move to their spouses home and take care of their in-laws instead of taking care of you. Some will leave your village to go to school, and maybe move to the US and send some money back (money which you can’t really spend on anything, because the latest political uprising means that no one is bringing trucks into your area anymore.)
Wouldn’t it make sense, in such a lifestyle, to have a lot more kids than we have here? Kids are a woman’s insurance policy and retirement account all rolled into one. Without a lot of kids, there’s a good chance that no one will be around to take care of her when she can’t take care of herself.
It’s a different world. While I’m not an absolute cultural relativist (I do believe that there are some things which are just WRONG, culture be damned), in this case, you have to understand the economy, medical system and political system of a country to know what decisions would be best for those people. They aren’t the same as ours, unless you have some plan to give them better prenatal and childhood medical care, social safety nets, better banks and less political instability. In other words, if their life doesn’t look like ours, the decisions that are good for them won’t look like ours.
