Investor’s Business Daily highlights an interesting development in the business world.

To hear Hillary Clinton and Bernie Sanders, you’d think that taxes can go up to 60% or even 80%, and businesses and investors will just … pay up. But the growing number of businesses stampeding out of high tax areas suggest that they’re very wrong.

We got more evidence of that this week when CKE Restaurants, the corporate parent of Hardee’s and Carl’s Jr. restaurants, announced that they are relocating to Nashville, Tennessee.

Hardee’s will move its headquarters from St. Louis, Missouri, to Nashville, Tennessee, one of America’s fastest growing states.

Oh, and did we mention that the state has no personal income tax?

Meanwhile, the Carl’s Jr. move puts more egg on the face of California and the political class in Sacramento. Hamburger fast food chain Carl’s Jr. was founded in California and for years has been headquartered in Carpinteria, California. The highest income tax rate in California is 13%, so moving to Tennessee, where the tax rate is zero, will save the company millions of dollars on taxes a year.

Yes, we know that CKE’s official line is that the firm is relocating because it has less need for office space as it consolidates operations. But the company executives say this with a wink. Tax savings are a big factor, as is the stifling regulatory environment on the left coast, where businesses are treated like villains and rich people as cash dispensers for big government programs. It’s not a coincidence that CKE’s CEO Andy Puzder has been one of the leading critics of high taxes and onerous rules in Washington D.C. and Sacramento.

Raise a Monster burger in salute, as we’re reminded once again that state tax rates matter.
