The problem with sin taxes is that they even further increase the divide between rich and poor. The wealthy won't be concerned if they're spending twice as much on booze, as it's such a small fraction of their income. But the working class may be denied one of their few pleasures - even if they were perfectly capable of keeping their consumption at reasonably healthy level. Even worse than taxing alcohol is trying reduce car use by taxing people off the roads (without significantly improving alternatives). That's taking away vast numbers of opportunities from those who need them the most.
