Wait, hold on, are you saying that you're aware that when taxes go up, tax revenues goes down, every single time it's ever been tried in all of US history at a regional level?
Turns out that this has not proven to be the case.
I think you misunderstand the Laffer curve. Laffer suggested that when tax rates are increased, the amount of revenue generated due to the tax would increase to some point, then at higher tax rates start level off and then to decrease, since there would be a point at which people would stop earning money if the government took too much of it away. There has always been fierce contention as to where that peak of the Laffer curve is.
The difficulty is that there never been a good analysis showing where that peak is. The US, for example, had a top marginal tax rate of 91% in the 1950s up until 1963, yet not only did corporate presidents not only stop working, the economy was booming.
So, no, the statement "when taxes go up, tax revenues goes down" is not supported by history.
