Ya, the bottom in the developed world, and especially in California, is much higher. In china you can find a moldy room in an apartment building basement (no window!), or even sleep in the restaurant you are working in (many people live in their shops in Beijing, and I don't mean above them in something like an apartment!). For food, there are plenty of places that cut corners to keep costs down, you'll live but you might get cancer later.

Pre-Katrina New Orleans was popular because survival was similarly cheap, not for the same quality of survival, but the bottom possible was lower.
