I read your post very carefully oldspice.
No-one could judge whether a person was unwilling or unable to get a job. As there is no visible difference between the two. The end result being the same........ no job!
You appear to be judging ALL teenagers by the experiences you have had which, although to be expected, is unrealistic and unfair.
I am talking from the experience of knowing some of these teenagers personally, not just from a teachers perspective.
You do not have to be trained or qualified (well or otherwise) to be intelligent enough to realise that such a law could not possibly suit all 16 year olds.
But perhaps the ones who are at school for the money are simply trying to get along as best they can in a world that as far as they can see can promise them or offer them nothing.
I personally, IF I were a professional, trained to deal with difficult young people, would be happy to see them in my classroom, knowing that the probable alternative to that in the real world is to have them out on the street or sitting in a hovel somewhere stoned out of their minds.
I am assuming that you knew the kinds of problems that you would be expected to deal with when you took your extremely difficult and emotionally stressful job oldspice?
When you have been spat at, sworn at and physically abused for simply doing your job, perhaps you might feel the way I do.
As a professional trained to deal with these circumstances I would sincerely hope not.
