Wealth inequality on the scale we see today is DEFINITELY a problem, it destabilizes countries.  However, dealing with the problem solely as a "tax the rich" solution is no solution...it is PART of the solution.....the rich should be taxed.  That said, another PART of the solution is to stimulate growth thus producing decent paying jobs.  If you simply tax, eventually . you run out of taxpayers.....if you don't provide incentive for growth,  you stagnate.  The two go hand in hand...but in today's world, it is POPULAR to "stick it to the rich"......and it resonates with the people...as MOST people are not rich.
