The thing is, as a country, we do have a lot of really serious (interlinked) problems. The fact that we have nearly 3 million people too sick to work is absolutely shocking.
What is more shocking is, that in any sort of clampdown, they are probably going to screw over the most vulnerable, who really need the sickness benefits. Unfortunately, the ones cheating the system will still be able to easily get away with it. And there are obviously in that nearly 3 million people, quite a significant number playing the system. Like a pp mentioned: "My neighbour gets benefits because he has such bad anxiety he can't leave his house. I would have sympathy as I have suffered anxiety that bad except in my case I did not leave my house for several months. He leaves his house almost every day to work cash in hand, go shopping, walk his dogs, go swimming etc." The dude is working cash in hand!!
Thing is, many are needing NHS help and are on months/years long waiting lists, getting sicker.
Anyway. I didn't vote in the last GE and won't be voting this time. No party can solve this. We are really really fucked and actively making things much worse. My jaw hangs open when medical schools tell students with 4 A stars to fuck off for example. I have a painful condition at the moment and have had to pay for private help. If I hadn't, I'd be totally debilitated with pain. It's a really quick simple condition to solve if you can actually access care.
