No way will this stop with the billionaires

Reason: "'Billionaire' Tax is a Bait-and-Switch To Gouge the Middle Class" - "Supporters of a "billionaire tax"—an idea being pushed both nationally and in California—claim it will impact only those who can "easily afford it." In fact, it's a Trojan horse. The next step will be to come after middle-class retirement funds and middle-class homes."

Absolutely true, just like the federal income tax was only aimed at the "rich."  What's funny (to me) about the "one time" billionaires tax is that nobody believes it will be a one-off tax.  Everybody believes California will blow the cash on boondoggles like high-speed rail and then come back again.  Then when the "rich" can't be dinged any further, it's time to hit the middle class.

For the children.
