As the so-called ‘sugar tax’ comes into being, it’s worth remembering just how poor a piece of policy it is. The sugar tax is regressive, it is ineffective and it is illiberal; any Liberal government worth its salt would repeal it.
The pre-amble to the constitution of the Liberal Democrats commits the party to both the fundamental value of liberty and ensuring that no-one is enslaved by poverty, the sugar tax fails on both these counts.
First and foremost the sugar tax is illiberal. If we accept that philosopher John Stuart Mill’s ‘harm principle’, the idea that power should only be exerted over an individual against their will if it is to prevent harm to others, is a cornerstone of liberal thought, then quite clearly the sugar tax fails this test. The consumption of sugary drinks poses no threat of harm to others, and as such the state has no business attempting to reduce their use. Whilst you could argue that the ‘harm’ to others associated with the consumption of sugary drinks is the additional strain this may put on the health service, if you were to follow this argument through to its logical conclusion you would advocate taxing gym memberships, as injury sustained through excessive exercise would too place a strain on the NHS. Clearly, this is nonsensical.
To add to this, not only is the sugar tax illiberal but it is also regressive, as it will disproportionally affect those on the lowest incomes. This is both because they are more likely to consume non-diet soft drinks than wealthier individuals, and also because tax rises such as this will take up a larger proportion of the poorest individual’s budgets. Evidence suggests that for individuals with a high sugar diet, taxes do little to reduce their consumption, and as such the sugar tax is all cost and no benefit to those whose disposable income is already low. Far from lifting people out of poverty, the sugar tax further condemns them to it.
