@Toodaloo1567 "Would I pay £35k out of my retirement lump sum for an insurance product to avoid the prospect of having to sell my home for care? Hell yes."
Who would you pay the £35k to? No commercial insurance company would offer such a product.
Who would provide the healthcare or retirement care that you think you've purchased for your £35k? No provider would entertain such an idea.
The only possible provider would be "the provider of last resort" - i.e. the government-funded healthcare service.
Your proposal might have some merit if everyone with a certain level of assets paid £35k into the national taxation kitty - the million richest people doing so would provide £35,000,000,000 which would go some way to paying for the nation's requirements. But this is at odds with your distaste of paying an extra penny in the pound NI. And the people who would be required to pay the £35k are probably the same people who are screaming about how unfair inheritence tax is, how they are "net contributors" rather than "scroungers" and how they would hide their money offshore, put it in Trusts and otherwise use any means possible to avoid paying this tax and letting Starmer or Reeves get their hands on it - voting instead for the likes of Hunt, Sunak, Johnson and Cameron who deliberately underinvested in vital public services so that their chums and donors could pay less tax.
