I agree. Biological pressure is for an individual to spread their genes the farthest. The race no longer goes to the intelligent and the productive, it goes to welfare bred hos and gangbangers who can work the system.
C. M. Cornbluth got it right more than fifty years ago in
The Marching Morons. 300 years from now with the current rates of reproduction, society will consist of 99% idiots and 1% people who can think.
Now all you have to do to spread your genes the most in the US is screw anything with legs, vote for increased welfare spending, then sit back and collect.
