WSJ: "Joel Kotkin: The Great California Exodus"

"California is turning into a two-and-a-half-class society. On top are the 'entrenched incumbents' who inherited their wealth or came to California early and made their money. Then there's a shrunken middle class of public employees and, miles below, a permanent welfare class. As it stands today, about 40% of Californians don't pay any income tax and a quarter are on Medicaid.

It's "a very scary political dynamic," he says. "One day somebody's going to put on the ballot, let's take every penny over $100,000 a year, and you'll get it through because there's no real restraint."
