Not sure if you travel much. But please to pay a visit to South Africa, Pakistan or some other places like those and drive around a bit. Any place with high birth rates, and you'll see, just like in Idiocracy, smart educated caring people have less kids to do a better job raising them than the animal-humans in some of the third/fouth world places. The population growth rate has gone down, yes, but the population is still going up.
It is well documented the growth is largely in under and undeveloped countries.
Current annual birth rates are ~ 130,000,000 - about the same as it was in 1980 - but, all the smart countries, Japan, EU, USA, etc, are hanging up the wedding tackle and all the retards are keeping it up.
Also, try giving a steak dinner, a hot shower and a car to drive to work for 7 billion every day. Aint gonna happen anytime soon .
