Thoughts on Government controlling births and ETC

In todays class we had discussed how the government has say on different things when it comes to pregnancy. Like they are able to take a child away when they are in danger and its against the law to abuse your child otherwise its child abuse , etc. But then we were saying how they cant control how many kids a mother can have. like this one lady has 18 children and keeps having babies , and no one is stopping her. I do think that the government should step in at one point when it gets out of control because if you cannot support the children, you shouldn't have them because you dont want to put them threw a miserable life!
i dont think that the government needs to go to the extend like they do in China where they restrict only two children per a family . i think that if you can afford to take care of alot of children , so be it , but if you cant there should something to stop them from ruining more children's lives.
Another thing that we brought up in class today was the question of why woman go through so much horrible technologies and stuff during birth? as a class we agreed that it was to ignore the pain . a woman these days will do anything to get rid of the pain! When i asked myself this question i said to myself that i would love to have a natural birth and all but then in the end after i feel all the pain i would ask for the numbing to take act and do anything for the baby to come out faster and get it over with. like i mentioned in class earlier everyone is doing the "faster procedure" because it is now " normal" but still not natural... whats natural is become un-normal. when i think about this, i can relate it to many things, like its natural to have body hair but we shave it all off because its "normal" to. There are many things like this that are natural and once normal but have no became un normal!
