The WFA fiasco was because it wasn't thought through and the cut off was stupid! We expect more from the "professionals" such as top politicians, senior civil servants, etc., who should have known it was stupid.
It wasn't the "idea" of means testing the WFA that was the problem. If they'd initially given it more than 20 seconds of thought, they'd have come up with a better way of means testing at a more sensible threshold.
Quite simply, it affected too many people.
By contrast, relatively few would be affected by an increase in age for free prescriptions as relatively few are aged between 60 to 67 AND not already receiving free prescriptions.
Likewise, relatively few pensioners will be working over the NIC exemption age, and many of those working will be part time and not earning enough to be liable to pay NIC.
Likewise not many pensioners will have homes that would fall within a new higher CT band.
There'll be an outcry about anything any party does, but the main thing is that the protesters will struggle to get widespread support if the change is considered "fair" by the majority.
The WFH was widely regarded as unfair and stupid, hence the outcry. It was entirely avoidable. Likewise the recent PIP changes - they got it wrong AGAIN hence the outcry. They need to start thinking about what they're doing and stopping making changes on the hoof based on sixth form debating society level of politics!
