Earlier I saw a little back-and-forth between WTF and Lusylad on the "Laffer curve," what the "sweet spot" that maximizes revenue might be, and a few other things.
(Way too many posts for me to go back, find them, and quote them, so I'll just toss in a couple of random comments.)
First, I think the revenue-maximizing rate and the optimal rate are different, since the need for revenue needs to be balanced against the desire to impose a high enough rate that an excessive level of deadweight loss occurs.

A good example is the capital gains tax. Many students of the issue believe that the revenue maximizing rate (which might be around 28%, according to a number of studies) is higher than the rate beyond which some "lock-in" effects begin to occur. If investors are disincentivized to sell an asset and redeploy the capital to a "higher and better use" in an investment with better prospects, the whole economy may be burdened, not just the individual investor.

There are lots of taxes out there - federal/state/local income taxes, payroll taxes, sales taxes, capital gains taxes, etc. Only a simple-minded simpleton would speak of revenue maximization (or optimization) without reference to the specific tax, since there is such a wide variety out there, like orchids.
And yes, there are very real trade-offs to consider. Seeking to find some elusive, imaginary, revenue-maximizing "sweet spot" is a fool's errand if it ignores the impact on growth, inequality, and efficient capital allocation. Only a simple-minded simpleton would fail to see and acknowledge this!
Some of those simple-minded simpletons can't stop ranting against imaginary straw men called "supply siders" who supposedly claim any & every tax cut ever enacted since the time of Adam & Eve has "paid for itself" by unleashing more revenues than it cost.
But of course, careful readers of eccie know that you, tiny and I have only suggested this is often true for capital gains taxes, and we have repeatedly rolled out historical data and graphs to support our point.
How many times do we have to repeat ourselves to be heard above the constant, annoying din of the simple-minded simpletons who spam this forum with their ignorant generalizations?
