The carbon tax idea is utterly incoherent: Let's imagine the left is completely right about global warming. How does a carbon tax help reduce carbon emissions? China's energy grid creates more CO2 per unit of energy than ours does and their factories also produce more CO2 on average: Very simply, creating something in China produces more CO2 than creating the same thing in the US does. The carbon taxes will cause production to shift to China because the tax will increase the price of US goods. This in turn will actually result in a net increase in carbon emissions---both because, as I just mentioned, China produces more C02 for a given amount of output and also because those products will then have to be transported farther before reaching consumers.
What I don't understand is how the World Economic Forum fails to account for the effect that world trade would have on their policy. What kind of chicken shit economists are these people? Really, a World Economic Forum neglected to consider the effects of world trade? Did they get so caught up in their cliches and cocktail parties that they forgot the little bit of economics some of them hopefully learned in school?
