Lietaer's success stories do not surprise us. They are what we would expect since we would advise similar measures as those taken in the stories.
Similar measures, but not the same. In particular, we do not see in his analysis a need to firewall the rich away from the poor using exclusive currencies. The need appears to be present in several of his success stories, however, because several successful cooperative currencies were terminated by legal action to enforce the central bank's monopoly on currencies. There lies one weakness of cooperative currencies. It is relatively easy for the rich to outlaw them. Alternatively, the rich could simply buy them and manipulate them.
Thus for all the effort and thought that Mr Lietaer and his associates are putting into cooperative currencies, we doubt it will have any lasting effect. Exclusivity is also required in our currencies.
