So hypothetically Nick, you loose your job for whatever reason. No fault of your own, let's say, but maybe the company you work for goes bust, requires redundancies or whatever.
You're educated (obviously), but it's not easy to find work in your field.
So you go for something temporary and lower paid while you're looking.
You redundancy and savings start getting abit low and you've still not found a 'better' position in your field.
The company you took the temporary job in then makes some cut backs. You were last in, so the first to be layed off. And it was a short term temporary contract this time, so no redundancy.
Again, you're eager and looking for work, but you've been out of your original field of work for some time now and it's getting harder to compete. So you're now competing with other people looking for lower paid temporary jobs... but emplyers are claiming you're 'over qualified'.... it's becoming a vicious circle and harder to find work, even though you're clearly keen and eager.
You are now one of "These People" you mention.
I'm not denying the benefits system is flawed, and there are certainly people claiming far more than their fair share, but it's not all malingerers and scroungers.
