All major Economists understand Edison, from John Kenneth Galbraith to Milton Friedman, they have all understood the scam. It's just that nobody dares oppose the central bankers. Bretton Woods was created because one understood that nations with vast amounts of natural resources would become immensely rich and before interest on their national currency issuance could take hold they would be able to escape such debt and indeed hold too much of other nations fake debt on their currency. All the idiots here suggesting Edison did not understand economy are dim-witted nincompoops who have never read or understood anything more complicated than Ayn Rand. after 25 years of economic studies every serious economists knows this one.
