Bill Mitchell is on it again – this time regarding the moralist language used regarding debt. This is not a uniquely German thing, also the Netherlands and Finland frequently sprout this kind of language. Together with this piece, I suggest David Graeber’s book “Debt: the first 5000 years.”
I am not entirely sure about Mitchell’s mention of Catholicism though. Also regarding Graeber’s book, I think the obsession with debt as a moral issue is much closer to Lutheralism and Calvinism though. It might very well be in itself a reaction (dating to the Reformation) to Catholicism, with their gold and corruption.
