You are wrong. What do you think the period of government austerity was all about after the credit crunch?
Ideological persecution, with a view to pushing those in penury even further into the mire, making them ready for the deregulated exploitation that is sure to follow hot on the heels of Brexit. Oh, and pandering to right-wing idiots who genuinely believe that the 'problem' with the welfare state is that some people 'depend' on it.
It was absolutely nothing to do with 'balancing the books', as proven by the fact it singularly failed to have any impact in that regard.
There is only so much it can tax people/borrow
No, there's only so much a Tory government is willing to tax before they start worrying about their electoral viability, and before they start having their donors breathing down their necks.
Why do you think there is a limitless pot of money?
I don't think it's limitless, and have never suggested it is. But I understand how the welfare budget functions.
Let me take a wild stab in the dark, you aren’t a net taxpayer, are you?
Your stab in the dark is not only wild, but missed completely.
Now remind me; which benefit or entitlement has your disabled child been deprived of because someone else made a fraudulent benefit claim? Be specific please.
