Bloomberg View has an editorial on income inequality that makes some sensible points, among them:
Most Americans, no matter how humble their circumstances, don't resent the wealthy so much as strive to get rich, too....Some imbalance is good. Imagine a tax system that would redistribute income so that everyone came out roughly equal. Entrepreneurs wouldn't be motivated to innovate because they wouldn't be able to reap the rewards. Fewer risks would be taken, and economic growth would stall. It would be convenient to blame the super-rich for stagnant middle-class incomes. It would also be wrong.
The editorial goes on, less sensibly in my view, to call for increasing the estate tax rate to 45% from 35% while decreasing the exemption to $3.5 million from $5.1 million.
