What is your point?
Of course benefits for working age people should be means tested.
How would cutting benefits improve your life?
Are you serious asking this question?
If yes, let me try - 25% of my taxes go to welfare bill. If you worked you could check your HMRC self assessment page and see the split. It's 25% of all my taxes!
Cutting benefits would force significant part of population into work, they'd grow economy and pay taxes, no matter how small. So less tax take and more tax generate. The amounts saved could be invested in defense, education, NHS, police, roads, etc. This would also allow to reduce some taxes, e.g. employers NI, so they could hire more people and grow economy even more. It would also allow to reduce personal taxes at some point.
So cutting benefits bill would benefit all taxpayers, me included, hugely.
As to your ongoing "there are no jobs" - there are jobs, plenty, just not necessarily desirable ones, and we have to import labour en masse from abroad because our system allows locals to sit on their bums doing nothing. Then after 5 years this cheap low skilled imported labour is finally allowed to get ILR and gets access to all benefits and then bring families in. Rinse and repeat. These people do nothing wrong, they try to get the best out of the system. But the system is very wrong and needs fundamental rethink.
And yes, whichever party will promise shake up of benefits system will get my vote (unless it's Reform).
