Why not go further and encourage the right kind of people to procreate? And the "right kind of people" are?
No-one with Lou Gherig's disease? (Stephen Hawking)
No-one with deafness? (Beethoven)
No-one with deformities? (Charles Steinmetz)
No gays? (Turing, half of the Hollywood entertainers)
No Møøse limbs? (who kept learning alive during Christian europe's dark ages)
No drug addicts? (Poe)
Straight hair? Almond eyes? Dark skin?
Swell, let the government pick who's suitable for bleeding, and who's suitable for breeding.
Just like any other domestic animal...
The right kind are married couples. Unfortunately for the "alternative lifestyle" crowd(yourself perhaps?), study after study has shown that children raised with a male father and female mother that are married aren't as screwed up as children in single parent homes. Right now the government encourages single teenage girls to have a baby outside of marriage. Over 70% of black babies are born out of wedlock and look at the incarceration rates of black males. My wife and I are penalized right now by the tax structure for being married and employed. We can't afford to have children, but we are penalized for being married. Why not encourage couples to stay married and encourage married couples to have children? Nahh, lets encourage gay "couples" to adopt babies and ignore illegal immigration to keep the population up to pay for social security instead.
