I am not advocating that low income workers pay higher taxes - in fact they should be exempt. I am saying that if you are from such family, progressive tax ensures you'll stay in your lane.
> That figure is misleading, because it includes a set of expenses like social security, health insurance, government pension plans etc. Corporations don't pay that and that's why the difference may seems so big
My number is based on what you get in your pocket from your salary (plus employer's national insurance that is most of the time hidden from the payslip) I didn't include local taxes (like council tax) and so on. Corporations are supposed to pay Corporation Tax, but they can too easily transfer profits offshore and largely avoid that in contrast to SME who mostly pay this tax.
Progressive tax ensures that person from poor background will stay poor.
