Interesting point of view and graphs. Is the US different today than it was in the 50's and 60's when tax rates were at their highest? A lot of people agree that raising taxes pulls money out of the economy and will hinder job creation.
DEAR RICH FOLKS: Get Ready For A (Tax) Revolution In Which Your Money Will Be Taken Away
...... In the first decade of the 2000s, super-low tax rates, super-cheap money, massive borrowing, and many other factors fueled an unsustainable sugar-high boom that has since turned to bust. And now the country finds itself saddled with colossal debts (in aggregate, including consumer debts, much higher than those after World War 2), huge budget deficits, and enormous inequality. And tax rates on the richest Americans are still near their all-time lows.
If history repeats itself, our financial problems will eventually be solved, but not without a lot of time and pain. And part of the solution will likely be much higher tax rates, especially on the richest Americans.
So enjoy today's low rates while they last.
