A life on unemployment benefit ?

Unemployment stands at around 2,500,000
900,000 people have been out of work for over a year,
of these 467,000 – have been unemployed for over two years.
of these accord to Iain Duncan Smith 300,000 have been unemployed for over 3 years.

As you can see, the longer time goes on the fewer people remain unemployed.

If things continue at the same sort of rate,the number of people unemployed for 4 years or more will be
about 150,000,  at 5 years 100,000

So who exactly are the families that have had three generations without a job.Largely an urban myth or a number so extremely small it makes me wonder why we are so concerned about people who don't want a job when we seem unable to provide jobs for people who do.  And where does 3 generations take us back to.  A miner or steelworker or manufacturing worker who lost their job in 1980.
