Unfortunately we currently live in a world in which public services, such as NHS, Education, Emergency Services, Benefits for the poor and disabled need money in order to operate. And as such, reducing VAT by a further 10% would just leave these VITAL and MORAL and IMPORTANT services without the funding that they require.
I'm not about to discuss the efficiency of these services, or if they need to be remanaged, or whatever - point is, everyone should have the right to healthcare, education and emergency services (law enforcement, fire control, etc) - to deny them that because the system requires that they pay sums to private companies is ridiculous. I'd rather not exist in the backwards USA. Thanks.
Japan manages all the same services at a fraction of the cost per person and with much better results .... while having a lower GDP per capita than UK (despite having a lot of "innovation" occurring there)
