Now, let's see - if that income between four and five million a year should represent some entrepreneur's share of a new startup and you tell him you're going to confiscate it if he makes it, what happens to the startup? Is "disincentive" in Dr. Gardner's vocabulary? How about "common sense"?
Where does he come up with 4 million, anyway? Sounds unequal to me. Level everyone off to $50,000 and call it a day.
