The crux of the issue is the public's misunderstanding of speculation and the productive role it has in a market economy. The pro-FTT crowd view speculation as pure gambling, with no beneficial side-effect. That is not the case. Illiquid markets create distorted prices, which are then acted on by producers and consumers alike. When producers invest scarce capital into business relying on distorted prices, they often lose - either creating too much supply in a market that has enough, or neglecting capacity expansion in markets that don't. This destroys capital and increases the cost of all goods, which the consumer ultimately finances through higher prices at the checkout = reduction in living standards. So what makes liquid markets? Speculators. Even though speculation provides no direct benefit, the indirect benefits it provides are fairly-priced liquid markets, which the real economy then uses to make production choices that effect everyone. This is why speculation in futures was allows to begin with.
