I think that this is misguided.
They are most concerned with Dims raising their taxes, not OUR taxes.
When
their taxes are raised everyone will definately suffer the fallout, and the very first thing that will happen is an increase, or an expiration of the lower rates, in taxes on capital gains, real property transactions, investments, dividends, and corporate income.
My investments will return a profit near zero in those scenerios, and capital gains on real will push down much of the rest.
I can move investments offshore in that case, but one must be prepared for that.
