Letter: European tax union is bound to follow from a single currency
Your support helps us to tell the story
From reproductive rights to climate change to Big Tech, The Independent is on the ground when the story is developing. Whether it's investigating the financials of Elon Musk's pro-Trump PAC or producing our latest documentary, 'The A Word', which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging.
At such a critical moment in US history, we need reporters on the ground. Your donation allows us to keep sending journalists to speak to both sides of the story.
The Independent is trusted by Americans across the entire political spectrum. And unlike many other quality news outlets, we choose not to lock Americans out of our reporting and analysis with paywalls. We believe quality journalism should be available to everyone, paid for by those who can afford it.
Your support makes all the difference.Sir: Proposals to unify European tax rates (report, 16 January) should be no surprise. As a matter of economic logic, tax union is an inevitable consequence of monetary union.
Countries outside a monetary union can use exchange rates to offset their ups and downs. For example, bad-weather failure of the fruit crop would cause severe economic hardship throughout Spain. But then the peseta would fall, it would become cheaper for people to visit Spain or buy Spanish goods, and balance would be restored.
A member of a monetary union does not have this option. It may try to revive things by taxing less and spending more, but that takes time to work and just stores up problems for the future. No, its only real hope would be to campaign for large welfare transfers from the union.
Thus when US states suffer - when Florida's fruit crop is ruined by frost, for example - they can do little more than petition for "federal disaster area" status, so that they qualify for federal support. Faced with hardship among the citizens of a member state, the EU authorities could hardly resist such an appeal, with EU taxpayers footing the bill. A coherent stabilisation policy for the union would require a coherent tax policy.
In other words, a single currency implies a single welfare policy and a single tax policy. So these proposals for a single tax regime should not surprise us, and we should expect proposals for a single European welfare policy in due course.
