The joke is that they hold taxpayers to ridiculously high standards, to the point where the concept of $600 of unreported income is something the government will harass you for. While they can just accept billions of their own spending going unaccounted for without a second thought.
And yes someone running their own small business struggling to survive is not worth taxing. Even if they were paying “what they owe” they would contribute nearly nothing compared to the rich people. And suffer far more for it.
