A x B/A doesn't equal C, it equals B.
Your math is as bad as your economics.
Joe, I will confess you got me on that one. My algebraic formula does not work, and does not fit the effect that has been described. Try this formula:
A x ((100% - A) x B) = C
Where A = tax rate from 0 to 100%, B = the economy, and C = tax revenues.
This formula has A influencing both C directly and C indirectly by also influencing B, which we know does happen, and which you also acknowledge. The formula also matches what we would expect at each end of the curve, hypothetically, and that is $0 in tax revenues if the tax rate is either 0% or 100%, this being in a purely capitalistic system where the government gave nothing back to the people to provide for the essentials of life in the form of food, clothing, and shelter.
We know that both of those scenarios would fail of course because 0% tax rate allows no money to run any government, which we seem to all agree is necessary to some extent, although at least the people would be able to live, but in a rather uncontrolled society, and 100% tax rate would cause mutiny, widespread tax evasion, or worse because the people would need to receive something for their labors in terms of food, clothing and shelter at least, either that or simply all die.
Joe, I am not attempting to come up with a magical formula here, obviously, but having a little fun here with a principle that obviously has some kind of formula in the economic world. After all, I believe the laws of supply and demand are real and do operate. As you rightly point out, other factors could be plugged into it, but we are not claiming to etch the values in stone, only to demonstrate a principle of tax rates as they relate to the economy and resultant tax revenues. Surely, Laffer understood this as well, and to denegrate a formula based on its inability to be precise misses the point that his curve is clearly demonstrating, that being its overall principle.
