Wilhelm Roscher,
Principles of Political Economy…
“ The efficacy of the repressive hinderances to over-population either consists in immoral acts or easily leads to immorality. Until a "surplus" child has died, what a series of troubles for good parents, and what a chain of evil deeds for bad ones, to say nothing of the poor child itself.Further, every man, no matter how short or long his life, requires a large advance of capital and trouble which he has later to return to society through the activity of his riper years. If he dies before his maturity, this advance has been made in vain. ”
