Griper Blade: A GOP Economic Myth Bites the Dust

It's one of the most enduring myths in American politics; that if you increase taxes for the wealthy (or, in the right's favorite BS term, "job creators"), the rate of employment will take a nosedive. Nothing about this makes any sense at all, but with a media environment that values a false "balance" above truthtelling, it's much easier to gloss over that fact. What the right is saying when they make this argument is that it would be too expensive to make profit -- a ridiculous claim that ignores simple math, not to mention logic.

So, in our current political and media environment, even obviously bogus claims need to be debunked. And two top economists -- Nobel Prize winner Peter Diamond and John Bates Clark award winner Emmanuel Saez -- probably felt more than up to the task when they took it upon themselves to bust this rightwing myth. In a Wall Street Journal op-ed, Diamond and Saez set the record straight.

The share of pre-tax income accruing to the top 1% of earners in the U.S. has more than doubled to about 20% in 2010 from less than 10% in the 1970s. At the same time, the average federal income tax rate on top earners has declined significantly. Given the large current and projected deficits, should the top 1% be taxed more? Because U.S. income concentration is now so high, the potential tax revenue at stake is large.


According to our analysis of current tax rates and their elasticity, the revenue-maximizing top federal marginal income tax rate would be in or near the range of 50%-70% (taking into account that individuals face additional taxes from Medicare and state and local taxes). Thus we conclude that raising the top tax rate is very likely to result in revenue increases at least until we reach the 50% rate that held during the first Reagan administration, and possibly until the 70% rate of the 1970s. To reduce tax avoidance opportunities, tax rates on capital gains and dividends should increase along with the basic rate. Closing loopholes and stepping up enforcement would further limit tax avoidance and evasion.

But will raising top tax rates significantly lower economic growth? But will raising top tax rates significantly lower economic growth? In the postwar U.S., higher top tax rates tend to go with higher economic growth—not lower. Indeed, according to the U.S. Department of Commerce's Bureau of Economic Analysis, GDP annual growth per capita (to adjust for population growth) averaged 1.68% between 1980 and 2010 when top tax rates were relatively low, while growth averaged 2.23% between 1950 and 1980 when top tax rates were at or above 70%...[CLICK TO READ FULL POST]
