That's as maybe. We're talking about how much some extra spending would cost us. I was only pointing out that with more than 50 million people in the country a billion is less than £40 a head. Are you saying that you couldn't afford (or would begrudge) £40, or even £200, for properly funded public services?
Decent progressive taxation would mean that people who didn't have much wouldn't pay any more, while the comfortable would. I'm not even getting into the cuts in corporation tax, or financial juggling.
As I said, if you think you can pay negligible tax and still have first-world provision of healthcare, transport, water supply, Trading standards, road cleaning and surfacing, policing (add your own favourite) then you are living in cloud-cuckoo land. If you don't want to pay taxes then emigrate to the USA, somewhere in Africa or another failing state and see how you like it.
