I recall seeing a chap on Question Time saying that the NHS was founded to look after a certain sized, certain aged population funded by a proportionate budget. The first two have increased but as he said to the audience, any political party that says they will take more of our money to make the NHS work as intended is pretty much guaranteed to lose votes.
So as he said, everyone votes for the party that says less tax/NI, but then complains that public services get worse.
I thought he made a lot of sense (he wasn’t a politician so he had a head start there) and maybe it’s time to acknowledge that more is needed to address it. Maybe they should also get people like this chap in to advise on it.
