This is why so many of your arguments fail; you substituye assumptions for facts.
That would be an entirely valid point if it were put honestly. Unfortunately, as is your habit, it was NOT. Which is why you cut off the quote mid-sentence.
To 'assume' that our tax system is at least as progressive as the US and probably a little more, is hardly a journey into wild assed guessing.
Is it your belief our income taxes are LESS progressive than that in the US? Because that is the only case in which you might have a point to make here.
