I'm curious how new tax schemes like the proposal Sweeney is criticizing get vetted. It's probably impossible to determine actual economic effects of radical tax reform in advance. Further, from a rational perspective there's no incentive for the best minds to advocate loophole closure in tax schemes as there's more value in exploiting them. I wonder if this is the kind of thing CNNs might be good at simulating some day.
