The President's Latest Bad Idea
A sizable body of work in public finance suggests that consumption taxes are preferable to income taxes. Completely replacing our tax system with a better one is, however, hard. Retirement accounts, such as IRAs and 401k plans, are one way our tax code has gradually evolved from an income tax toward a consumption tax. The use of these accounts should be encouraged, not discouraged.
By the way, exceeding $3 million in such accounts is not very difficult for an individual who is financially successful and frugal. Under current law, a self-employed person can put about $50,000 a year in a SEP-IRA. If he does that every year for 40 years, and his savings earn a return of 5 percent per year, he will retire with about $6 million.
So, yes, President Obama's $3 million constraint would be a significant disincentive for saving. It would move the tax code in the wrong direction.
