That is the easiest one to “refudiate”, (thank you Sarah Palin).
The trick is to use this comeback, Just to clarify, what you are saying is the Bush Tax RATE Cuts decreased Tax Revenue, right? You will ALWAYS get a perplexed look, and then the Libtard will ALWAYS say YES.
At that point you explain that the Bush Tax RATE Cuts affected all Taxpayers and overall Tax Revenue to the Federal Government increased 35% in only four years after full implementation. At the same time, the “Rich” paid a larger portion of the Tax Revenues than ever, while the bottom 50% of earners paid less.
The follow up question is key. You ask the Libtard what would happen if all the Bush Tax RATES were repealed? Since they are clueless at this point, you tell them that the people in the lowest Tax Bracket will see their Tax Liability increase 50%, while the “Rich” will see their Tax Liability increase 10%.
Hit with an increase in Taxes, the Rich Small Business owners will cut back in other areas, NOT hiring additional employees being first on the list of cutbacks. Ironically, had those additional employees been hired by the greedy Rich guy, they would be hit with the 50% increase in their Taxes.
Classic Catch 22 situation.
The one I use is I'll ask them: "OK... just what percentage of the taxes SHOULD the Top 10% of earners pay?" They'll usually answer with, "I don't know, they just need to pay more"... but I try to pin them down to a number... when they come up with one they usually say somewhere between 40-60%... Then I tell them, "Well, then you're proposing to give them a tax reduction, because they already pay 71% of the taxes."
