That was blown out of all proportion, tbh; the UK used to have a tax carveout for the upper-middle-class which allows unused pension funds to be inherited tax-free, and this was in practice used as a tax avoidance mechanism, and that's going away, but it really isn't a particularly big deal in the scheme of things.

(Or there was another change to the privileged treatment of farms and family businesses, but again, you're not talking about a huge change.)
