I'll tell you a little story, OP, on a level you might understand.
Once upon a time there was a man. The man left school, completed an apprenticeship and got a job. It was a hard, physical job working with lots of nasty chemicals (and when the man was many years older he found out those nasty chemicals had destroyed his physical health and left him with an illness that will probably kill him). But nevertheless, he worked hard at his job.
After the man had spent twenty years in this job, a Conservative prime minister changed all the rules, and the man found himself made redundant like thousands of other people where he lived. Unfortunately, the Conservative government hadn't thought about what these thousands of people would do when it closed all their workplaces, but they lived far away from London so it didn't really matter.
The man had been given some money when his job was taken away, so he used it to retrain for a different job. He worked at his new job for nearly ten years. Shortly after starting his new job, he started to suffer from a horrible mental illness. He worked and worked for as long as he could but eventually the illness was so bad that he couldn't do his job any more. He changed to another job and worked for as long as he could, but after only a few years he was even more ill and his company told him he would have to stop work altogether.
Fortunately there was a Labour government in power by this time, so because lots of different doctors all agreed the man was "disabled", he was able to claim for some money to pay for the extra things his disability cost him, like his prescriptions for all the different tablets he had to take every day, and taxis to his doctors appointments because he couldn't remember which buses he needed to take because the illness made him lose his memory. It wasn't a lot of money but it helped him to live.
Then one day the Conservatives came back to power. Now the man has been told he won't get this money any longer. He has to try to get a job instead. All the doctors still say he is disabled, in fact they say he is worse than ever. They all agree he is worse than when he had to give up even his easy job a few years ago. The man is in his 60s now. His physical health is bad. His mental health is bad. But the people who the Conservatives put in charge of the money for disabled people say they don't care. They don't care that he worked for as long as he could even when he was ill. They don't care that no employer would take on a disabled man in his 60s in deteriorating health. They don't care what his doctors say. They don't care that they make the man feel even worse, that he cries with stress, that he thinks about committing suicide. They have targets, and he is an easy one. So they are stopping his money and he will live unhappily ever after...for a little while, anyway.
And that's no fucking fairy tale. That's my husband. That's his life. That's our life under Cameron and Duncan Smith. And we are far from unique.
So there, OP. That's why I hate this government. Because they take the dignity and humanity from those who can least afford to lose it.
