For What It's Worth...

If you look at the top marginal tax rate in the United States since 1948 and also at the rate of real GDP growth in that same period, there's a +0.212 correlation. That is to say, a higher top marginal income tax rate has been slightly associated with a higher rate of economic growth. I know this really isn't good data, but doesn't that maybe suggest that we should be a little skeptical of the claims that cutting taxes for the rich is essential to a strong economy? Just a thought.
