Your logic is a little fuzzy - I’ll let you re-read your own post to figure out why - but I’ll happily answer your first question:
How is it a change of subject to say the goc wastes money?
(Context: people saying that they would happily pay more tax never say how much more, instead changing the subject to rant about money they think that the government has wasted.)
It’s a change of subject because it means that you are avoiding the difficult and uncomfortable question of how much more tax you, personally, in pounds sterling, are prepared to pay each year to fund public sector pay rises.
So far we’ve had one person say that she’d pay another £3k per month. Provided her childcare, which she says costs £3k a month, became free, of course. And train tickets. And other things too. So that’s not going to help much, is it?
We’ve also had some vague pontificating on ‘taxing all the billionaires and millionaires 1%’. Which apparently will raise billions. Taxing them on what? There are different types of taxation: income taxes, transaction taxes (like VAT and stamp duty), taxes on the estates of dead people, like IHT, and taxes on crystallised gains, like CGT.
Which of those would you apply to these billionaires and millionaires? If they haven’t earned any U.K. income that year, or died, or crystallised a chargeable gain? Or would you invent a new wealth tax especially for them? Have you ever thought about the complexity of bringing in a wealth tax? plenty of other countries have, and have abandoned the idea. I can imagine the howls when somebody living in a semi in London ‘worth’ more than £1m is told to find 1%, or £10k, stat. Do you think that those people, and the billionaires, will happily hand over the cash? Or might the latter relocate to another country, thus spending their money somewhere other than London’s finest hotels, restaurants, car dealerships and retailers?
