A very interesting financial concept and challenge that could apply to any government.
The current bankers and corrupted or influenced politicians and their corporate counterparts would be the losers. Are these the ones lobbying and funding the campaigns of said politicians and parties? Does money and influence like this help win elections? If so a concept like this would never get even looked at.
Maybe enough support and courage in a lower level of government to test this concept. Then the public push for it at a higher level but in tandem with the current method but on paper only. This test would require a huge investment in time and money and there never appears to be enough of each. It is obvious the current method needs an overhaul so is this the answer?
