To get section 8 you must meet a list of requirements. Just being unemployed is not enough. Even if you qualify, there is limit to how total many section 8s are given out. So there is a waiting list of several years, during which time you must still qualify. You can not just sign up on that waiting list. There are small windows open at random a few days a year when they will accept names. No leasor is required to accept section 8 people and very few do. So even if you get a section 8 voucher, you still need a lot of luck to find a place. Thus the streets are paved with homeless.
