I don't think carers get anywhere near enough support from rhe state in terms of healthcare, social care, respite etc, and they never will from a Tory government.
But CA is rarely paid in isolation unless you have a high level of capital or household income that stops you claiming other benefits. If you're looking at whether the level of financial support is fair, you need to compare the total, not just one element.
Carers allowance is a total insult. I don’t even understand people saying it isn’t paid in isolation. For many it is paid in isolation because they have partners who work and are therefore not entitled to any other benefits. If they were not caring they would probably be employed and would have a proper wage which fully reflects the hours they put in.
