According to an article in the Telegraph: LINK.
WHY? Because the SYSTEM (of state and capita)l treats children in accordance with how it treats the rest of us: as a developing “human resource” and consumer (or client), rather than as developing human beings.
To understand WHY, one has to view society and its development from a human-evolutionary, i.e. Darwinian, perspective. Evolution adapted human nature (emotions, motivations, gratifications and behaviour patterns) to a tribal environment which has now been replaced by the artificial, socio-economic environment of civilisation, which we are ILL adapted and thus corrupted to survive and seek perverted forms of “success” in.
But there is nothing we can do about it without first recognising this and developing an understanding of it. Trouble is that “moral authority” forbids us from taking a Darwinian view of human society, because that’s what those wicked and discredited social Darwinists did.
