Many could actually. Some could move to lower cost of living areas. Some could choose to get education or training that enables them to get a job in the future. Some could get jobs, some could certainly move to where there are jobs. Some could choose to quit recreational drugs and alcohol. Some could use their welfare or disability payments and move to lower cost of living areas. Some who dislike living with others could choose to put housing above that preference and could afford move into group housing. Many do these things actually, I have heard many first hand stories from people getting themselves out of homelessness.
So how are we weighing up all these choices and deciding who is a "valid homeless" and who is not?
