Too Long; Didn't Read
The idea comes from a book called Investing In Human Capital (published in 2004) by economist Miguel Palacios. The book is notable for helping to develop alternative models of student finance, such as income contingent loans and income share agreements. Instead, the financier is paid back by government directly from the tax revenue collected from that student in future. This particular model covers only a few pages of the book, but it’s an idea I keep coming back to. It is elegant, maybe a bit radical, and it seems to have fallen through the cracks of history.
