I know two prostitutes, one of them is constantly in my thoughts as she's basically the poster girl for these type of sanctions. A smack addict, pushed into prostitution by her dealer/pimp boyfriend, kids taken away, mentally ill with learning disabilities. About 2 years ago she at least had a flat, was contactable and was doing slightly safer work online. She suddenly found herself being evicted, and no landlord would give her the time of day because she relied on Universal credit. Cue a downward spiral of street walking, physical assult and rape. We haven't heard from her in a while, her dad frequently tries to find her, though he has to contend with people assuming he's a John which makes it even more difficult.
She was a very fragile woman teetering on the edge and universal credit fucked her over it. I will never forgive this government for this, though I'm not so naive to believe that this shit hasn't been happening forever.
