Yes, I think double taxation is murky and shit. Why should anybody pay 12% of their income towards possible health and social care costs and then have to stump up a chunk of their house value at death?
Sure, there are strong a guments for inheritance tax. I agree that I can't write that off as unfair double taxation, but the dementia tax definitely is.
A person on the average UK salary could expect to pay £150,000 of national insurance between the age of 20 and 60. Not forgetting that employers pay similar into the pot. £300,000 per average earner...shouldn't that be enough?
