Bernard Lietaer

Bernard Lietaer (wikipedia: en:) made his name implementing the convergence mechanism for the European single currency, and was named the world's top currency trader in 1989.

In The Future of Money: Creating New Wealth, Work and a Wiser World, 2001, sometimes contrasted with John Grey's False Dawn, Lietaer offers an "upbeat" take on money. He says "we are largely ignorant about our money system", addressing what he sees as the four "megatrends" currently driving society:

Lietaer argues that "all crises contain hidden opportunities", which leads him to his central thesis that "we are now engaged in a structural shift of the world system, and this shift offers an unprecedented opportunity to give birth to Sustainable Development" which he spends significant time trying to define.

Lietaer's account of the philosophy of money, the liquidity of currency and the nature of personal savings are described as "entertaining" by Jerry Brotton.

Other reviewers however consider it "a devastating and controversial analysis of the challenges facing monetary systems... an agreement of society to use something as a medium of exchange...now being placed under an unprecedented strain, due to a wide range of factors (from the creation of cybermoney, to social and political issues).

Speed of change threatens unrest if "instability of the monetary system continues to spread. The global monetary crises of the 1990s (Mexico, Russia, Asia and Brazil) proved that money is modern society’s central information system – equivalent to the nervous system in our own bodies.

In order to prevent a global monetary meltdown, a unique vision of sustainable abundance, and the mechanisms for achieving this monetary reform, is proposed" by Lietaer.

Seeming complementary currency is the mechanism most favoured by Lietaer.
