The idea of seeking a “solution” to the homeless problem at the community level is meant to get people thinking about homelessness in a challenging way. If we could solve the homeless problem, what would it look like? On a grand scale?
When a solution is sought at the community level, we are asking for something impossible, given the constant flow of homeless people in every city. But seeking a solution is to describe a set of ideals, some of which are achievable, some of which can only be goals to shoot for.
For example: Helping people get off drugs, which is extremely difficult, but necessary to get a job.
