Housing Bubble

People have been talking about home prices being overvalued for years. LA, methinks, is awfully susceptible to a bust - as is San Francisco. At some point, the value of certain investments has to be overvalued, speculation cannot go on forever. The example used in the article is the stock market prices of the 1990s. Anyhow, it makes me feel better to be investing in school versus a home, knowing the home prices are overpriced. (I think school is overpriced as well, but I doubt that will go down anytime soon.)
