Even outside of morality it's a straightforward issue. Investments in children benefit the whole economy and society, for decades. If a person can't see that then they could be immoral but they might just be stupid.
Plenty of human beings genuinely and earnestly believe that investing in the "wrong kinds" of people would be harmful to society as a whole. This is not limited to regressives or conservatives either, with plenty of savants on tumbler and reddit reinventing eugenics "against rich people this time".
