Why doesn't the government start to sterilize people at birth. In 50 years it will be just an after thought like getting a license to drive a car to have a kid. Some requirement's could be IQ, if you have a job and for how long, how much $$$ you make to be able to afford the kid, and a psychological evaluation both mother and father. Having a kid should be a privilege not a right.
The way we are going now, dumb will rule the future because smart people are not multiplying as fast as poor uneducated people. This is a serious problem.
