There is a surprisingly good correlation between “fairness” and the wealth of nations. A major component of unfairness is corruption and it is very plausible that the more money is sucked out of the economy by corruption, the less productive it is.
The other component of fairness is inequality and we can show how the combined effect of corruption and inequality give a better correlation with lower GDP than either alone. This indicates that it makes little difference whether money is siphoned off into the pockets of either the extremely rich or the corrupt. It is just that the former are identifiable and the amounts quantifiable.
The idea of “Efficient Money” is to establish alternative ways of funding enterprises, such as Crowd funding, which do not involve the resulting earnings disappearing into the pockets of the non-enterprising.
