I think you nailed it! In the past....it was something else but still something that distracted folk from the criminality of their own government.
The stupid thinking that originally thought a tax on income was inherently a good and decent thing......simply shows the caliber of folks who inhabit government edifices (both elected and hired).
actually the original tax was on income. which by definition was derived from a source. investment income not wages. The crooked supreme court changed the definition of income to be “appurtenance to wealth” i think it was IRS v glenshaw glass
