I've whined about this before, but here goes again.
That's just the way it is in California. A "single-family" home less than $500K is either less than 800 square feet, a complete and utter heap with structural damage, or it is rural with extremely poor commute access. Who would be willing to live there other than a family that has been low-income and is willing to put up with that crap? And, no, jobs really don't pay much more out here at all. We do have more intrinsically high-paying jobs (tech, entertainment, finance, etc) then many other parts of the country, which is how you fill so many $1 million tract houses, but your average joe working his average job simply does not buy a house here unless he has a spouse that makes much more than he does, he lives like a hermit, and/or he has a lot of help from family or inheritance. Those that attempt to bend these stipulations foreclose in five years. Upper-class jobs and wages mean middle-class living here. Middle-class means lower-class living. And those who work service jobs are simply fucked up the ass. That's why you get three families in that $450K "low income" house, because it takes six full-time salaries to pay the mortgage.
I currently live in the Bay Area and make what is considered a competitive wage for my field, which requires a college degree and a specialized professional skill set. I cannot buy an acceptable place to live on my salary. Ever. Acceptable to me means safe, clean, adequate parking, and no roommates other than my S.O. I save at a rate that will likely make me a multi-millionaire before retirement, but with rents high to match the market, I will never make up enough ground on a down payment to keep up with the market. I will always fall farther behind. Luckily my parents and my fiancee's parents have pledged to help with a down payment, which is extremely generous of them. But even then, we will need to wait indefinitely for our incomes to rise to cover the resulting jumbo mortgage, high property taxes, insurance, etc.
We are caught in the same place as many others of our generation, where we have plenty of money to buy late-model cars, big TV's, go out to eat, etc, but housing costs have inflated so far beyond that of everything else that we can't buy a traditional middle-class place to live even if we live very frugally and forgo all those traditional middle-class luxuries.
The middle-class baby-boomers (like my parents) are all fine, though, because they bought their houses long ago, have tiny little mortgages, and rode the wave of ballooning equity in the late 90's. They can sell and buy again with impunity, even though their incomes aren't really any better than anyone else's. Hell, I make more than either my mom or my dad make NOW. Yet they own two houses and plan to retire to beautiful Monterey, while a starter condo is merely a dream for me. If you weren't a land-owner already in 1995, you may never be able to catch up.
The obvious response is "so why live there!?" The answer is that aside from the housing situation, it is simply the best region in the country to go about the basic business of having a job, raising kids, etc. There are plenty of nice places to visit elsewhere, but to live full-time? California is tops. And there are just too many people with the same opinion.
Cliffs: Housing prices skyrocketed, leaving non-owners and children behind. Kids grow up, can't buy a home even though they make more than previous generation. Homes in ghetto cost $450K, and young middle-class workers choose to stay in apartments instead.
