UK has property taxes too and its pretty shit tbh. Council tax, there are bands based on what your house was worth in the 90s (yes really…) and generally the poor will pay a higher % of their income. I have a pretty small bungalow, 60m². One of the lowest bands and pay £1600 a year on a house that cost £230k. The most you can have to pay is £4200, beyond that point regardless of how much more expensive your house is the tax rate doesn’t increase.

The original plan of the tax was a fixed rate per person. This among other things is why many people were keen on the idea of digging a hole so deep that we could hand Thatcher over to Satan personally.
