How is that even a fair comparison? If the OP is genuinely entitled to the benefits - how is he stealing?
As others have said, fix the flawed system - don't go after the people that claim because the system allows them to.
No hes not. The system doesn't say "If you would be better off sacking in your job and turning to benefits then do it." Its there to help those that cannot work or are looking for work. If you quit your job to go on JSA then you are fiddling the system and you should not be entitled to a penny. You can't claim JSA whenever you don't like a job or feel that you would be better off unemployed.
Go to a job centre and tell them that you would like to sign on because you just quit your job and would be better off without it and see what they say.
