Not valid data, not data showing any understanding of the nature of economics across different demographics. Nothing to show the other taxes paid beyond income tax, vat for example, which are paid at a much higher rate of income percentage for those with lower incomes.
No understanding of the fact that those who earn less typically spend a greater percentage of their income, therefore vat is paid to government from the cyclical movement of that money while the wealthy spend a much lower percentage of heir income, saving, investing and hoarding the remainder therefore taking those funds out of circulation.
The economy needs a large number of people on a lower income constantly living hand to mouth to keep itself moving, because money that is saved and hoarded has income tax paid on it then disappears form public funds to the individual for decades.
The fact we all live and die and have a finite time on the planet and you're happy to condemn the many to 'relative' poverty so the few can be wealthy is so utterly baffling. It is also so short sighted, you are 1 accident at work, small blood clot in the wrong artery, as yet undiscovered genetic malady away from being plunged into poverty at all times. Most disability is acquired. And if someone acquires an illness or disability before they manage to save enough to survive that financially well there they are reliant on a system that you want to remove.
That is why I am confident you don't have a PhD. In anything.
