This is what I do with the economic illiterates (80%+ of the USA population):
I ask them 2 questions.
1. How much tax would be collected if rates were 0%?
2. How much tax would be collected if rates were 100%?
If they’re too illiterate to figure it out, I explain how both questions have the same answer. If they get that, then they must agree that lowering the tax rates can increase tax dollars collected.
We, the literate, must ALWAYS correct someone when they talk about lowering and raising TAXES. That is incorrect verbiage. Only RATES can be raised or lowered. Once they get that, got to the 2 questions and repeat.
It is truly amazing how many deny the fundamentals of the Laffer Curve.
