California varies WIDELY by county. I'm slightly above middle class in Sacramento County, in Santa Clara County with the same salary I'd be in the lower half of middle class, in San Diego county I'd be in the upper half of middle class and in Shasta County I'd be rich LOL
People just need to realize that costs of living can be crazy different in different areas, even ones that are only a few hundred miles away (that's not targeted at you specifically TVGuy, I've just seen comments the last few days that indicate some people don't get it). Most of that difference is due to housing costs.
But to get back to the topic - Californians may want to look into making charitable contributions to the College Access Tax Credit fund, if it fits their giving goals. Money goes towards college grants for needy students, and you can get a 50% California tax credit for the amount you contribute. It's been around for awhile, but the credit was mostly used by folks trying to avoid California AMT - I suspect with the federal tax changes, it could become more popular with people just trying to maximize the amount they are able to give to charity. I believe other states have charities that give similar tax credits, but I'm in California, so I've only heard of this one specifically.
