Guy Kawasaki has some interesting observations on what makes Silicon Valley work, for those wanting to replicate its success. Some of them are quite unexpected:
High housing prices. If houses are cheap, it means that young people can buy housing sooner and have kids. When they have kids, they can’t take as much risk and don’t have as much energy to start companies. (I have four kids—I barely have the time and energy to blog, much less start a company.) Also, if houses are cheap, it’s easier to “make it big,” and you want it to be hard to make it big.
