[...] Even a modest increase in the total tax burden on the top 1 percent of earners to a 45 percent rate, far lower than its postwar levels, would bring in an additional $275 billion in revenue. [...]
the obvious rebuttal to that is that such an increase might spur an increase in tax avoidance/evasion, or would lower the incentive to draw such a high salary. that's not addressed in this article, unfortunately. my response to that: you'd also need better enforcement + closing of tax loopholes, and as for the lower incentive, that might actually be a good thing in a macroeconomic sense, depending on where the money comes from (need to think about that more, esp in a global context)
