I'm convinced that none of the people who are stealing from trains in California lack food or a roof under which to sleep. However, I think they are overwhelmed with sights of the rich and glamorous while at the same time underwhelmed with their lives and future prospects. Too many people want to get rich quick, and that's most true in American cities. Trains with valuable cargo that is easy to carry become a sitting duck when they are stranded for a prolonged time in a US city.
