Other than basic math, I have no evidence.
Prove your basic math skills by grasping what I'm about to explain to you.
It is entirely possible that 2 + 2 = 5.
You must believe that if you persist in the belief that Higher Taxes = Greater Revenue while ignoring the imperical data showing that Higher GDP = Higher Revenue.
Yes, if you believe that lowering taxes increases GDP, if you think that there is a cause and effect there, then you have a point
Again you are going on the attack rather than defending your own "voodoo" economic theory that Higher Taxes = Greater Revenue. Since you clearly believe that Raising Taxes = Higher GDP, then we are asking that you make that argument. That doesn't mean attack "trickle down" theory, that means explain and defend your "trickle up" theory.
I believe I already did, but perhaps not.
Are you referring to the post about 16% of X being larger than 15% of X in regards to raising tax rates? The underlying problem with your "simple math" is that empirical data shows it to be false. X is always GDP (the factor which determines higher or lower revenue) and that is the only real variable, the percentage is almost always static at 18%. Your equation treats GDP as static and the percentage as the variable, that is incorrect.
So if you can understand that 16% of X is larger than 15% of X, why are you having such a problem understanding that -
regardless of the tax rates - revenue remains 18% of GDP? It's pretty simple to grasp once you realize that
tax rates are not the determining factor and accept that
GDP is the determining factor.
Just how would you increase GDP?
According to your "trickle up" theory, raising taxes increases revenue, and since revenue is always 18% of GDP, raising taxes must magically increase GDP. We are waiting for you to make that argument and explain to us how that is possible.
Of course spending more than we take in has everything to do with it.
That isn't what you said, you claimed lowering taxes caused the debt. Whether taxes are higher or lower, and whether revenue is larger or smaller, makes zero difference so long as we do not spend more than we take in... Therefore messing with the tax rates is not the cause of debt, spending is the sole determining factor.
Lowering taxes while not cutting spending did cause a deficit.
Raising taxes and still spending more money than is brought in through revenue will also cause a deficit... In that scenario, according to your fallacy of confusing correlation with causation, raising taxes caused the deficit. Again, whether taxes are raised or lowered does not matter so long as spending does not excede revenue. I don't know much simpler the math could be on that point but you still don't seem to grasp it.
