People on low incomes generally pay proportionately MUCH more in tax than people on higher incomes.
That's such a strawman. Yes, if you have less money, anything you do spend that money on that is subject to tax is automatically a higher proportion for you than someone who is higher paid. But that doesn't mean because someone low paid pays a higher proportion of their wages in things such as VAT that the overall level of tax they pay is bumped above other higher paid people, higher paid people still need to pay for the same things as lower paid people, and still pay the same VAT.
I'm not a low earner, I'm not rich either, but I still have to pay the same amount of tax on a tank of petrol, and my grocery bill as a lower earner, all the while after paying out X times more in income tax and national insurance contributions than they do. That's just the way it is, and would never change, not without something stupid like a tiered means tested VAT rate or something as equally insane.
Plus they spend their money, keeping the economy moving, rather than keeping it in offshore bank accounts where it does nothing to help anyone.
I love it when this point pops up, you'd think the amount of times people mention it, that we'd be awash with tax avoiders littering the street, I can't walk down the street without tripping over off shored tax avoiders. Meanwhile back in the real world, they are probably few and far between. The majority of the population are either low paid, or in the middle, and while the occasional high profile off shored tax avoiders gets the spotlight, that's all it is, a spotlight, it's not a representation of the wider population.
So anyone on low pay is a darling, keeping the economy turning by spending all their money, and everyone else is a tax avoider who's off shored themselves hording their gold, no-one in the middle at all?
Also, there seems to be a lot of conflation between society and economy in this thread, they aren't the same.
