those who are really in need
There is a Govt scheme called "Access For Work". I don't get PIP, never tried to claim it, but I do get AFW workplace support to the tune of about £3k this year. By the time you factor that against the taxes I pay, I'm a slight consumer of Govt money because I earn £42-43k.
How do you feel about that?
If your gut reaction was "that's OK because you're working", then you're a hypocrite and have contradicted yourself. By definition, someone who can work with AFW support isn't "really in need" (your words) of State benefits because they can work, albeit with support. Therefore, the money that supports me should be rediverted to support people with missing limbs (or whatever your personal standard of "really in need" is). The fact that I would lose my job and hence my house, have to have my beloved CatOfHate euthanised or rehomed because I wouldn't be able to house or feed him, etc is irrelevant to that because I'm not "really in need" and therefore shouldn't get any money because of being autistic.
When people using the "you should suck it up and work anyway" rhetoric about hidden disabilities hear that I'm on AFW and say "that's different, you're working", I know straight away that I am actually dealing with someone who is just jealous that someone else isn't being forced to work. I know that "the country can't afford it" and similar arguments are just a figleaf for their jealousy. I know thus because these people are A-OK with the Govt spending money on me as long as it's solely to enable me to join them in wage slavery.
£50 to Rape Crisis says that "that's OK because you're working" is exactly what you thought.
