This is what the No 10 Petition says:
"At the moment, all food (including things like hotdogs and crisps) is subject to a zero rate of tax. But people who want to make a healthy choice and buy smoothies and juices get taxed 17.5% VAT. It's a simple step, and, as more and more people get their fruit in liquid form, it could make a big difference. Our research shows that at least 500 million more portions of fruit would be consumed each year if this happened. Since we all know that eating more fruit and veg is essential to being healthier, it makes sense to help people make positive choices."
Now, we all know that VAT is controlled by the EU and, whilst our local government in Westminster has some leeway, it is still severely curtailed in what it can do.
Still, there is an interesting comment in the official reply:
Dietary based taxes were considered by Derek Wanless in 'Securing Good Health for the Whole Population' -published in 2004. The report highlights a number of difficulties of principle and practice in any attempt to use the tax system to influence diet.
So, the idea of using taxes to affect consumption throws up "a number of difficulties of principle and practice", does it?
So remind me again, what is the justification for the massive fucking taxes on cigarettes and alcohol?
