(CNN) -- By now, most of us have probably heard that Mitt and Ann Romney paid just under $2 million in taxes on income -- virtually all from investments -- of just under $14 million for 2011, an effective tax rate of 14.1%. This is a low tax rate, lower than the typical middle-class American worker pays, especially when one considers payroll taxes, the largest burden for most Americans. It should concern us that individuals of Romney's wealth -- analysis has put his personal fortune as high as $250 million, not counting some $100 million in trusts set up for his five children -- pay so little as a percent in taxes.

In sum, the government is pitching in, in the form of foregone estate tax revenue, for @placeholder's and other rich people's presidential runs.
