I think, they should. Why would you have a child if you know you cannot support or feed him/her? Poor people need to stop fueling the world with more poor people. Poverty could be eliminated tomorrow if there is a will to do by the people at the top.
Populations grow in areas which were formerly agrarian, switching over to industrilization usually have populations growth. In impoverished societies, this can have negative effects when the transtion is poorly managed, or influnced by outside factors. When population reach a state of alluence, the societies reach a more static growth. People aren't going to stop having children because you think it would be good for them. having kids is one of about 5 basic desires people have to fulfill in life. I was brining that up to show how completly ludicrous it was. And no, it doesn't matter what you think, theres no way to get rid of poverty in a day, or a year with any amount of money. Money alone won't solve poverty, as poverty isn't soley a shortage of money and an impication otherwise shows a rather childish interpretation of poverty.
Human desire? I am human and I do not have that desire! I never said money (money is useless, however since we live in a money world, money is liberty.) is going to end poverty. I made a thread on this topic "how can money end poverty" weeks ago.
Well you're probably young, and either way the vast majority of people do. "Why can't they be more like me" is the wrong apporach to looking at poverty. You'll never be able to help people unless you put yourself aside. Money can help alieviate poverty, but it's much more complex then that obviously.
