The problem isn't lack of resources but where they are located. For the first time in history urban housing needs have overtaken non-urban housing needs (which may or may not be related to the fact that our economy has changed in the recent decades due to the decline in US manufacturing). In non-major metro areas there's a LOT of vacant homes and apartments.Many of our major cities are having crisis level issues with homelessness, not just in CA but nation wide. There's not enough infrastructure or money to repair the infrastructure (roads suck, we don't have enough water storage to last through the dry years any more)
i do agree that transportation infrastructure is in dire need of an overhaul. It's not that there isn't the money to fix it or people willing to take the jobs, but those in positions of power would rather spend it on other things, like the military and 17 benghazi investigations.
