The World could have avoided I think the present financial mess by adopting then the alternate plan, the one that was proposed in Britton Woods by the British. http://en.wikipedia.org/wiki/Bancor
Yes, Keynes did save the world, if only for a few decades. And not only that, I think any rework of an international monetary agreement must include:
– through the re-introduction of capital controls; restraints in the growth of credit; and the establishment of a • The taming of financial marketsKeynesian international clearing agency;
• "Upsizing" the state – empowering governments to respond to democratic mandates by wresting power over decision-making from unaccountable financial markets, and restoring policy autonomy to elected governments;
• "Downsizing" the single global market – by introducing an international trading system based on the concept of "appropriate scale".
And lo and behold, it appears that Ann Pettifor supports an exact same plan to save the world.
