You cannot explain to the "tax more" crowd that tax can only ever confiscate a part of existing economic activity. I don't know why, it's a perfectly simple and straightforward argument, but their argument is just "x pays a%, y pays b%, why doesn't everybody pay max(a, b)% ?". It's jealousy, really.
Now that's not to say there isn't merit to both sides of the argument that some level of tax is too little and some level is too much. But not in the UK. The UK is firmly in the tax too much camp, as is most/all of Europe.
If I want to pay someone to, say, be my lawyer. And the person I hire for that wants an iPad, then of every 1GPB I pay to the lawyer, 23 cents ends up as revenue for Apple (making revenue for apple is WHY that person wants to be my lawyer, in other words, it's the reason for there to be any economic activity at all in this relationship). 77 cents ends up in the governments' hands to spend (of which, I might add, the government spends about 104 cents). That's ... just not reasonable (and also why every UK company lawyer has to defend all the executives for free to keep his job, to cheat this system)
