I have to agree with you that population limitations are necessary. The things that need to be free or low cost are the methods of contraception. It is not the complete answer but just a part. One of the things I made sure my two daughters knew as they were growing up is that I didn't want them to feel that they needed to be in any kind of rush to run out and give me grand-kids. Go out. Get your feet on the ground. Don't have kids till you are at least 25. Let yourself grow up first. Make sure that the daddy wants to help you raise them. Also since diabetes runs on both sides of the family if you fall in love with someone who has the same history seriously think of adopting. Our genes are not so special that it worth risking a serious health issue on a baby. There are tons of children out there that need loving parents.
I have been telling my granddaughters (we have had them since they were babies) to finish high school, go to college, buy a car and a house so that if something happens, they will always be able to take care of themselves and any children they have. I tell them if they marry a guy who has all these things, he gets to keep everything when and if they get a divorce. Now, I know that is not always true but if they believe me, maybe they will do as I ask. The older girl, 18 this year dropped out of school and shows no signs of wanting to get anywhere in life but at least at this point she's not pregnant nor does she want children right now.
