Eduardo Porter has a Business Day article in the New York Times, Wednesday, October 19, 2016, “Bold Strike Against Poverty: A Check for Every Child”, link.
He explores proposals to go beyond the per-child tax credit proposals, to simply giving a grant (maybe yearly) for every child.
This brings back ideas that we see in the debate about paid maternity leave (expanded to paid family leave): you ask some people to pay for other people’s children – for other people’s marriages, for their sexual intercourse, to put it bluntly. It confounds an individualist’s idea of personal “moral hazard”, which was holding away in libertarian debates in the 1990s.
But the idea can also be related to proposals concerning universal basic income, or even (for overseas) to “give direct” style charities. Vox Media has especially promoted these proposals.
