Utter nonsense. While you can't balance the budget entirely with tax hikes, there is no logical reason to believe increasing the rate in top earners will result in reduced revenue.
There is however ample Evidence in the past. Dating back to JFK, Reagan and Bush, that lowering taxes, Especially on the middle and upper rates. Can in fact Increase Revenue. It is logic then to conclude that the Reverse could in certain Cases be true.
It really is basic Economics. Increased Taxes have a slowing effect on the Economy. A slower Economy means less is being taxed, Less people are working, etc. Now if the slowing off sets the increased Tax Revenue from the Increased %, Could in fact result in a net loss of Revenue.
Even Left leaning Economist, and People in this Administration, Under stand and Admit that increased Taxes run a real danger of Slowing the Recovery(Growth) of the economy. JFK, Reagan, and Bush all understood one thing. The Way to increase Revenues is not to increase taxes. It is to grow the Economy and thereby the Tax Base you are taxing. Bushes Cuts did indeed Increase revenue to the Fed. The only problem was Bush Increased Spending at the same time and built up Debt. However that does not change the fact that his So called Tax cuts for the rich, lead to a growth in Revenue. That is fact. And the same principle was proven true By Reagan and JFK before them.
