We've visited the homelessness crisis before. It's particularly bad in Los Angeles, but the same problem exists in other Californian cities (e.g. San Diego).
This video may be labeled a "parody", but there's an awful lot of truth in it.
My take on the subject is that as long as government is expected to provide the solution, there won't be one. Government sees only the opportunity to spend lots of our money, and create lots of new jobs for their bureaucratic drones, while ignoring the reality of the situation. In fact, it's in their best interests not to solve the problem - otherwise what would they do with all those lovely jobs they've created for themselves?
