The Laffer Curve makes a number of assumptions without evidence, most notably that tax revenue as function of tax rate is memoryless, when it obviously isn't.
This is ignoring the issue, even when accepting the Laffer curve as true, that the revenue maximising rate would surely be well above what would be morally acceptable to enforce (~75%)
