Jeremy Hunt believes that there should be a dedicated tax specifically to be spent on the NHS and social care.
What a bad idea!
If you don't think very hard, it sounds like a nice idea. More money for the NHS!
Or is it? If you have a "Health tax" that garners £10 billion per year, then hey! We could reduce the NHS money that comes out of general taxation by £10 billion!
If the NHS needs more funding (which is a separate question), then wouldn't it be a good idea to simply raise income tax, which would bear harder on the rich than on the poor? Rather than invent a whole new tax system, with a herd of civil servants to administer it, with bookfulls of legislation to enact it, and providing an whole new source of revenue for accountants as they sought ways to minimise clients exposure to this new tax?
If you want more money, raise income tax. And don't try to fool us into thinking that some new tax is ringfenced for the NHS.
