Angelinos are paying the price for it in their time, their health and with their wallets. However, I think moving LA towards higher density development (similar to a New York, London, Tokyo, Berlin) is the correct approach.
Why are people spending 2 hours in traffic and commuting 50 miles each way, every day? It is because housing is un-affordable closer to the jobs. Even run down houses in crime ridden neighborhoods are ridiculously priced.
