One of the three songs on the 'Revolver' album that was written by George Harrison was "Taxman".  We more than likely can't relate as to what inspired that song, however; with that being said the tax burden on people who earn way too much money, we can relate to the "Taxman" song and it's underlying theme.

"If you drive a car, I'll tax the street;

If you try to sit, I'll tax your seat;

If you get too cold, I'll tax the heat;

If you take a walk, I'll tax your feet."
