Ubundu, is happening in some villages in Africa somewhere if memory serves. I read an article months ago, early last year. It's some sort of Bank-less barter society. I've not got full details, but it sounded good enough for me. You must remember however that there seem to be people who don't understand the word enough. They accumulate 'money', and out it in a vault, and set up to accumulate even more, as if the ownership of money were an invisible safety-net against the vicissitudes of life. I do understand that it can be on a short term, but once one gets beyond the ability to hand count it, then it becomes an almost meaningless bulk that has no purpose.
