Wanting a child has nothing to do with the amount of money you have.
Why do you feel that way?
Because children can be raised by less wealthy parents too.
It's true that kids can be raised by poor parents, but money does play a big role in a child's health and success in life.  It is important to be financially stable before having children, if at all possible.
I mean if you can't afford it then you just have to not have kids.
I don't think it's fair to say you can't ever have kids. You should want to be financially stable and not struggling before you have them. There are many ways to make sure you have money, by having money saved or a job.
