The world is a laboratory and different nations are public policy experiments. Not surprisingly, the evidence from these experiments is that nations with more freedom tend to grow faster and enjoy more prosperity. Nations with big governments, by contrast, are more likely to suffer from stagnation.
The same thing happens inside the United States. The 50 states are experiments, and they generate considerable data showing that small government states enjoy better economic performance. But because migration between states is so easy (whereas migration between nations is more complicated), we also get very good evidence based on people “voting with their feet.” Taxation and jobs are two big factors that drive this process.
Looking at the census data and matching migration data with state tax systems, here’s what Michael Barone wrote. He finds (not that anyone should be surprised) that the absence of a state income tax is correlated with faster growth, which attracts people from high-tax states.
…growth tends to be stronger where taxes are lower. Seven of the nine states that do not levy an income tax grew faster than the national average. The other two, South Dakota and New Hampshire, had the fastest growth in their regions, the Midwest and New England. Altogether, 35 percent of the nation’s total population growth occurred in these nine non-taxing states, which accounted for just 19 percent of total population at the beginning of the decade.
And here’s Diana Furtchtgott-Roth, writing for Realclearmarkets.com. She uses the presence of right-to-work laws (which prohibit union membership as a condition of employment) as a proxy for the degree to which big government and big labor are imposing restrictions on efficient employment markets. Not surprisingly, the states that have a market-friendly approach create more jobs and therefore attract more workers.
The American people have been voting with their feet, the Census Bureau announced on Tuesday, leaving states with heavy union influence and choosing to live in “right-to-work” states with higher job growth where they cannot be forced to join a union as a condition of employment. …As a result of geographic shifts in population uncovered by the 2010 Census, nine congressional seats will move to right-to-work states from forced unionization states. Some winners are Texas, Florida, Arizona, Georgia, and South Carolina, while losers include New York, Ohio, Michigan, Illinois, and New Jersey. Over the past 25 years job growth in right-to-work states has been over twice as high as in unionized states.
This leaves us with one perplexing question. If we know that pro-market policies work for states, why does the crowd in Washington push for more statism?
Welcome, Instapundit readers. Since many of you might not be regular readers of International Liberty, the important lesson to learn from the Census data is that federalism is good because state governments have to compete against each other, and this helps restrain the greed of politicians. The same principle operates at the international level, which is why tax competition is such a powerful force for liberty.
