I wrote back in 2012 that California voters opted for “slow-motion economic suicide” by voting to raise the state’s top income tax rate to 13.3 percent.

Sure enough, having the nation’s highest state income tax rate has been bad news.

More and more companies and households are leaving the (no-longer) Golden State for zero-income-tax states such as Texas, Nevada, and Florida.

Unfortunately, it appears that California politicians aren’t learning any lessons from this exodus.
