In Vietnam, you'd see water dispensers and glass cases with free loaves of bread, all left out by private citizens as acts of charity. Plus, there are charitable eateries that charge less than a dime, or even nothing at all, for a plate of rice with vegetables. Though all these aren't too common, the poorest know where they are, so it's literally impossible to starve here.

As for places to sleep, you can rent a hammock overnight in a shared room for less than a buck. Again, you have to know where to go, and the poorest certainly do. That's why it's extremely rare to see anyone sleeping on Vietnamese sidewalks.
