> benefits the most unproductive(i.e. edge case poor and super-rich). While putting all the pressure on the middle class.

People say this about every country. I think it's just that countries benefit the poor more than they "contribute" b/c they have the least ability to do so and people want their governments to be progressive. On the flipside, everything is always easy for the super-rich, because they have tons of resources to employ armies of people that enable them to benefit from every loophole possible.
