actaully, that is not really true. If Hauser’s law was true, it would be evident in other countries or always evident in the US. But it is not.
Hauser’s law is therefore not an iron law of economics, merely an interesting coincidence in the postwar american economy.
and you also have to remember that marginal tax rates only tell half the story about taxes collected-—tax deductions, credits and loopholes are the other half when you have to look at revenues. You could have very high tax rates, but you could offer a plethora of deductions and credits, and therefore have in fact much lower taxes. Or you could have low tax brackets, but have higher taxes because you don’t allow deductions or loopholes.
Cause and effect.
Taxpayers will follow the path of less taxes, taking advantage of all benefits available.
