I think I'm right in saying (though correct me if I'm wrong) that most people are on unemployment benefit for only a short period of time and yet the impression is often conveyed that there is a huge swathe of work-shy people who have been unemployed for years. There are, no doubt, some people - who don't have the inclination or ability to work or who live in areas of very high unemployment - who may claim out-of-work benefit for many years, but I don't think they are typical.
I think there will always be people who, for a number of reasons including emotional/psychiatric issues, dysfunctional background/chaotic lifestyles, physical or intellectual incapacity, etc. etc., will find it almost impossible to obtain and hold down a job.
Although the unemployment figures have been significantly reduced, most of the new jobs are low paid and insecure - and many people have been encouraged to opt for a form of "self-employment" that does not provide them with a proper income but removes them from the unemployment statistics.
A substantial amount of taxpayers' money is being used to "top up" the very low pay that increasing numbers of people are receiving - and often from large, profitable companies that could afford to pay their employees a decent wage. It seems the British people are content with a policy that subsidises highly profitable companies (which, to make matters worse, are also reluctant to pay the proper amount of taxes) and yet see nothing wrong with making further cuts that will affect low paid workers and the unemployed.
As durhamjen says, the UK is a relatively wealthy country and yet substantial numbers of people are living hand to mouth and having to rely on foodbanks. With this government's announcement of further in-work/out-of-work benefit cuts, many families will find themselves in even greater difficulty. Cue more family breakdown, more psychiatric illnesses and more misery. What a disgrace in the 7th richest country in the world.
