Mr. Imm, I disagree.  The super wealthy pay the lowest tax rates in the country.  Corporations avoid billions in taxes.
True, those without incomes do not pay federal taxes but contribute just the same.

The top 20% own 85% of the wealth in the US and the top 1% have 50% of the total wealth in the US.

Many countries with a lower GNP than the US have universal health care, universal education and longer paid vacations, paid days off work and work less hours per week than in the US.
