In the case of breeding, what intellects wish for is irrevelant.
The hard truth is that trailer park trash will breed and multiply while the educated people have much fewer children. I have two only despite my wealth and intelligence.
So in the new future, given the demographics change, the descendants of the trailer park trash may very well call the shots, given the current trend of populism and democracy of one-man-one-vote system. We already see that happening in jiuhu, where the m&d population now outnumbers the chinks by a ration of 3:1. Back in the 1950s, the m&ds and chinks were at a ratio of 1.5 : 1.
