I use the term "scroungers" to appease the people who get wound up by the few real scroungers. In truth, I think scroungers are a problem largely invented by the right wind media and used by the Conservatives to anger people and win votes. But, it still stands that highly unqualified people are processing claims.
I always remember the case of my brother. He had a stroke after diving and travelling by air. It completely crippled the right side of his body. He could just about walk, but his right hand was useless. He was right handed which made him completely crack-handed. He could barely do any task that required hands.
Par for the course, the government assessed his condition and declared him completely fit for work, ignoring his disability and the fact that he had never worked a day in an office and was now expected to. And as he said, sure, I could probably do something, but who the **** is going to give me a job?
