Sam Bowman disagrees: Soda taxes
I'm a liberal. I'm interested in economics, technology and food. I used to run @ASI and I invented neoliberalism.
A tax on sugary soft drinks is the first step on the road to fat taxes and sugar taxes more generally. It makes little sense to tax sugary drinks on their own, rather than sugar more generally – a couple of Mars bars are just as bad as a bottle of Coke – but the Chancellor probably reckons that the public won’t care if he only targets soft drinks. Once the tax is in place, he will follow the lead of other ‘sin taxes’ and raise it higher and higher, and impose it on more and more things. The costs of this tax will likely be passed on to consumers in the form of higher prices, so it will be regressive.source
