If you've never claimed it, and don't even know what it is, maybe you should think twice before blaming the country's financial problems on it.
I've been a JSA claimant twice in my life. I was only successful once. Honestly the most degrading and miserable thing I've ever done. And this was years ago before things were tightened up. I didn't have to face sanctions like they do today.
I went in to the experience expecting to feel slightly guilty that I was getting 'money for nothing'. But they make you work so hard to jump through all the hoops- especially as a newcomer to the system- that in the end I felt that I had earned every single miserable hard won penny.
These days it's much worse. And disability benefits are even more demeaning. I have a friend who was a waitress. She suffered a stroke and was unable to go back to work. Every six months the DWP pay for her to go to Inverness where she meets an assessor who has been flown there and put up in a hotel, just so that he can say yes, you're still paralysed down one side.
It's not about saving money. It's about making people feel worthless.
