Tax rates and tax revenues are different animals.

Total tax burden on middle income Americans is now in excess of 50% if you include all taxes: Federal, Social Security, Medicaire, state and local income and/or sales, excise taxes, and esp. real estate taxes. This is no exaggeration. Just add them up one by one.

However, if you make $10million in dividends your Federal tax rate is 15%. No social security tax, and you probably get tax abatements galore for your companies, real estate, etc. Just look at all the states giving corporations and real estate developers tax abatements for just staying in their locales.

Your final statement is so wrong. The fiscal mess in the USA is due to the dwindling tax revenue from corporations and the upper 1%. Of course, waging 2 wars with tax cuts and bailing out Wall Street with no tax increases is doing huge damage.

Simple solution to this mess: 2% Wealth Tax on net worths over $10million (include all persons, companies, trusts, foundations, etc.). Keep this tax until the deficit is gone and the US debt is paid off.
