There are people in the SF Bay Area who have full time service jobs and can only afford to live in their cars. It should worry everybody when there is a large - and growing - segment of society that follows the rules and can’t scrape by. That doesn’t last for long.
You don’t need to worry about the crack heads, worry about the people who can hold a 9-5 and aren’t getting a living wage. All they need is a charismatic leader to organize them, and they’ll actually get shit done.
