Rok Spruk linked to the Tax Foundation's 2008 State Business Tax Climate Index rankings, where the first few spots (states with the least burdensome overall taxes) are consistently occupied by Wyoming, South Dakota, Nevada, Alaska, and Florida. The last few spots (states with the most burdensome tax policies) are conversely occupied by Rhode Island, New Jersey, New York, California, and Ohio.

I never thought of Wyoming or South Dakota as prosperous places, so my first instinct was to see how these states fare against New York or California in terms of how their economies have grown in recent years.

I found GSP (Gross State Product) data on the pages of the U.S. Census Bureau, plopped the data in Excel, and indeed:

A comparison from 2000 to 2005 shows that the fastest growing state economy was Nevada, 31.0%, followed by Florida, 26.4%. South Dakota is 9th, 19.8%, while Wyoming is 11th, 19.2%. These states were all among the first 5 in the Business Tax rankings.

Alaska was 38th in terms of growth, 10.5%, regardless of its favorable Business Tax ranking; but the reasons may be apparent. (Who wants to be exiled to Alaska when there's Nevada?)

On the other hand, Rhode Island was 23rd, 14.7%; California was 24th, 14.3%; New Jersey was 33rd, 11.8%; New York was 34th, 11.6%; and Ohio was 49th, 6.1%. These states were the bottom 5 in the Business Tax rankings.

So, yes: based on this simple parallel, it would seem like a favorable tax regime can be correlated with significantly higher growth.

What does this mean for you as an average citizen?

If an average person's purchasing ability follows the growth of the overall surrounding economy in the long run, then it means that, in 20 years, the value of things you can afford as a person living in Wyoming will double; whereas the value of things you can afford as a person living in New York will rise by only about 50%.

Even more drastically, it might mean that, in 20 years, the value of things you can afford as a resident of Nevada will triple; whereas if you're a resident of Ohio, it will grow only by 27%.

And this is just the difference based on differences in taxation among the states. Imagine instead what happened if the U.S. as a whole switched to FairTax.
