Don't worry about referencing WSJ. That data is all over the place. If all of the income of the top 1% or 2% was taken it still would not put a dent into the problem.

There is a problem with taxing high-wage earners that is never stated. These people, in general, are smart problem-solvers. You give them dis-incentives and they will withdraw.

This is the essential segment of society that supplies the vision and structure for everyone else. Disincentives these people and you gut the core of your nation.
