David Orrell quotes
The entire thrust of neoclassical thought is to argue that the free market economy is an efficient system that will optimize utility for all mankind, if only government will get out of the way. It therefore departs from classical economists such as Adam Smith, who recognized the importance of governments for regulating markets and preventing monopolies.
David Orrell
It has become increasingly evident, at least among those who aren't currency traders or true believers in the optimality of free markets, that it would be nice if this system could calm down a touch. One option is the Tobin tax, which would impose a tax of around 0.1 percent on currency trades, and act as a kind of damper on speculation.
