You may have missed his point: people have no idea how much they pay in income tax because they never see it! If they did, a Democrat could not get elected to the post of village idiot.
The left has been trying to prove trickle down did not work for over 30 years now. One radio idiot in Chattanooga and I got into on air years ago about it and his "proof" that it did not work after I confronted him with the facts about how much federal revenue rose during the Reagan years was "the deficit went up." Got cut off before I could ask him if he was personally overspending, got a raise and then spent additionally more than the raise, would he expect his household spending deficit to decrease? What I despise about people making those arguments is they know they are lying or deliberately obfuscating facts because they don't really care about the deficits. They just want more tax money to effect enslavement the population.
