He is applying the "indifference principle" to criticize high tax states with unfunded pensions. From Zero Hedge:
“If I were relocating into some state that had a huge unfunded pension liability, I’m walking into liabilities. . . And those are big numbers. Really big numbers. . . They will come after corporations. They will come after individuals. . . They’re going to have to raise a lot of money.”
BOTTOM LINE: A mobile asset, like labor, will move to where it can earn the most. Consequently, young, wealthy, and productive people will be drawn to states like Tennessee, Texas and Florida (which have low income taxes and relatively healthy pensions).
