This series is meant to illustrate the following points:
- ‘growth’ over time can be linear, natural or exponential. Nature is sustainable because its growth mechanisms are natural.
- the mechanism of compounding interest upon interest over time is ‘exponential growth’ which is unsustainable
- the growth of interest-free cash is minute compared with the growth of interest-bearing credit and the growth of the national debt.
Under its aims and objective, the UK Treasury advocates ‘sustainable growth’ on http://www.hm-treasury.gov.uk/about/about_aimsobject.cfm
