Quote from tomdavis:
A friend of mine in Sweden says the "I'm for the FTT if it's global" statement is a way for politicians to say they're for it, while really being against it.
Here's the situation: In most EU countries, the FTT has 65% popular support. But at the same time, many politicians are smart enough to know that the FTT will destroy their financial centers. They also know it will be virtually impossible to get the entire world to agree to an FTT, so that gives them an out; but at the same time they can pander to the public by saying they support the FTT "if it's global." It's a ridiculous game of "I'm for it, but I'm against it." It's crazy, but that's politics.
Put yourself in Cameron's position. Over 60% of the British public supports the FTT. But he also knows that the FTT will burn London to the ground. So he says that he'll support it if it's implemented across the entire world.
The Swedish and Dutch Finance Ministers recently said the same thing.
