I'm no Tory, but the amount of pointless desk jobs doesn't help (e.g. I recently saw a role advertised for 'Director of Fairness' at 75k a year, around 5 times what a nurse earns). If another party was in charge they'd just throw money at the issue, meaning there'd be more desk jobs like this and very little (if any) of the money would actually filter through to front line care, and the front line care workers.
Firstly someone needs to either make these pointless desk jobs obsolete or, probably more doable, cap any HR, administrative, etc.. desk jobs at no more than £30,000 p/a (more than generous). Once this is done, then investment is key because significantly more of the money will be going to help those on the front line.
