In the UK you can live off benefits your whole life if you so choose to do so and know the 'tricks'.
Plenty of pioneers I know claim benefits such as Housing Benefit, Council Tax benefit, Income Support, Job Seekers Allowance, Working Families Tax Credit... you name it, they can claim it. Which to me stinks because even though alot work part time, theres no reason why they couldn't work full time and support themselves fully.
Of course I don't apply this to those that are genuinly entitled to whatever kind of benefit, morally as well as literally.
We all make a mess of our lives from time to time
It's part of the process that you stumble as you climb
