This is why I think devolution is a bad idea. We already have an international race to the bottom on aspects such as tax rates and environmental impact, why compound it with devolution? In the UK, local authorities can set tax rates, but they can't carve out exceptions or change the tax schedule. Seems like a good system to me.
