Gosh Pilot, you've solved the entire issue of poverty and homelessness.  Let's see: teen who have fled an abusive home need to get a job; addicts and chronic alcoholics just need to "get a job"; Vets with PTSD "just need to get a job", severely mentally ill individuals "need to get a job", the developmentally delayed ( mentally disabled) need to "get a job"; abused women with childred need to "get job"; the elderly trying to live on Social Security need to "get a job."  You suggest that "most" homeless people are alike and all they need to do so "solve" their homelessness is to "get a job."

It would, in my opinion, benefit you to study homelessness and poverty and the many, many different issues which lead to those conditions.  You might also study the idea of Housing First, a program which has been very successful helping needy individuals take those steps toward working their way out of poverty and homelessness.  Simplistic solutions seldom represent real solutions.
