I'm assuming that they've not been to a "normal" UK carehome now. Its staffed with minimum wage workers who are in perilous conditions, with no support, time or backup. They are cleaning shit a piss all day long, and being shouted at for being foreign by the demented.
This framing is ridiculous. Elder abuse and neglect is rampant. Nursing homes are run like prisons and you're empathizing with the guards.
The solution is to pay these positions well enough to attract people who genuinely believe in the profession. But society optimises away from doing that because there's no obvious ROI outside of making running costs cheaper.
