There are of course plenty of people with genuine mental health problems and they do need proper provision but my experience from volunteering with a "collective" that was focused on these issue is that a proportion .. perhaps more than haf of the one that I saw were simply there for the ride. It was interesting to see how when the benefits system was tightened up just how many found jobs, what was also noteworthy was just how many of the one's who knew how to play the system though managed to keep their benefits and avoid having to find work and sadly a small who lost their benefits and ended up on the streets or worse. A weakness of the system has and still in the inability to filter out those who are playing the system and of letting those who truly need help to slip though the net.
