This is an interesting story about Brazil, vouched to be correct by a commentator who lived in Brazil at the time.
The “Unit of Real Value” acts as an extra and REAL measure and thus provides a real and stable yardstick in a sea that wobbles with ‘credit money‘ and ‘interest money’ – unrelated to any real value.
The smart aspect is the fact that ‘monetary inflation’ is separated from ‘price inflation’, and the financial economy is separated from the real economy. And ‘economics’ becomes real rather than a ‘soft, sociological science’…
Who else might copy this model that worked???
