Which benefits are you referring to? Unemployment insurance and welfare are generally time limited. Disability payments can last forever, specifically because those people can't work. (There is a small amount of disability fraud by people who are capable of working but choose not too, and are able to convince physicians to approve their claims.)

Benefits in a very broad sense. This includes both e.g. SF General Assistance payments and things like cleaning the streets from syringes, urine and poop on a weekly basis.
