It just occurred to me reading this.( http://www.golemxiv.co.uk/2012/04/vulturecrats/#comment-24762 Inflation could be seen as a sort of built in Debt jubilee, by stealth.
The doubling time at 2% inflation is 35 years.
Biblical jubilees were every 50 years or so. Implying an indexed jubilee rate of inflation of 1.4%
70/50= 1.4% Back of an envelope stuff, the property developer in me is taking a long time to exorcise.
This is a very fair blog discussing and trying to get to grips with the idea of Debt Jubillee, Reading the comments is helpful too.
