The so-called “progressives” love to talk about how their policies will create a worker’s paradise, but then why is it that day after day, month after month, year after year, people are fleeing liberal blue states for conservative red states?

The new Census data on where we live and where we moved to in 2014 shows that the top seven states with the biggest percentage increase in in-migration from other states are in order: North Dakota, Nevada, South Carolina, Colorado, Florida, Arizona, and Texas. All of these states are red, except Colorado, which is purple.

Meanwhile the leading exodus states of the continental states in percentage terms were: Alaska, New York, Illinois, Connecticut, New Mexico, New Jersey, and Kansas. All of these states are blue, except Alaska and Kansas.

The latest Rich States, Poor States document published by ALEC finds that nearly 1,000 people each day on net are leaving blue states and entering red states. This migration is changing the economic center of gravity in America ― moving it relentlessly to the South and West.

Travis Brown, the author of the indispensable book “How Money Walks,” shows that two of the leading factors behind this movement of human capital are 1) whether a state has a right to work law (half of the states do) and 2) how high the top income tax rate is in the state. Nine states have no income tax today and they are creating twice the pace of jobs than are high income tax states.

Data from the Internal Revenue Service (IRS) show a similar trend. Each year the IRS issues a migration data report which examines how many tax filers (and dependents) in the year changed their residency and how much income was transported from one state to another. The numbers for the most recent year (tax filing year 2013) are gigantic and put the lie to the claim that interstate migration is too small to matter in terms of the wealth and economic opportunity in one state versus another.

I’ve never met a Democrat who could come up with even a semi-plausible explanation for why families and businesses are hightailing it out of blue states. They are leaving states with high minimum wages, pro-union work rules, high taxes on the rich, generous welfare benefits, expansive regulations to “help” workers, green energy policies, etc. People are voting with their feet against these liberal policies.

But the underlying trend is unmistakable: Liberal blue states are economic dinosaurs. Will they change their ways before they go the way of Detroit and become extinct?
