Alcohol duty fraud: Action needed, say off-licences

Given the level of duty, this really isnt very surprising. The neo-liberals who run the world want low taxes on income, because people will evade high taxes, but dont seem to have worked out that exactly the same thing will happen with alcohol, tobacco and eventually petrol, assuming their argument is correct. Its OK to use high taxation to change behaviour, but not the behaviour of the rich. What happened to logical thought processes?
