I’m not happy to pay benefits to sham claimants who are taking the piss
Define "sham claimant taking the piss".
By DWP's own admission the number of fraudulent claims is minuscule, so by what measure are you determining who is a "sham claimant" and who is "taking the piss"?
Claimants do not set their own eligibility criterion, that's down to the Government, so it seems to me your notion of "sham claimants taking the piss" is nothing more than your resentment for the actual people themselves showing itself, because if you actually were concerned about the cost to the exchequer then the issue there is the policy, not the claimants.
Also, since the benefits in question here are still a tiny proportion of the overall welfare bill, it's telling that the subject of every single one of these threads is either families with multiple children, or the sick and disabled.
If you really were concerned about the "cost to the taxpayer", you'd be hopping mad about the absolute nonsense of retaining the triple-lock on pensions and the fact the UK State encourages large employers to pay pittance wages by ensuring they are topped up with UC.
No, it's invariably the two child cap, or PIP, or whining about skyrocketing claims for illness and disability without ever pausing to consider just why we have such and ill and unfit population.
