Yeah, couldn't possibly be that there were any actually good results coming from this. That's just an impossibility.
I don't think that's what GP is saying. This report would be more believable and more objective if it would have other types of metrics than just self-reporting ones.
There is a kind of people that function by finding edge-cases, questioning the results and posing uneasy questions when presented with a situation. Some might call them "haters", or nit-pickers, but I think their way of thinking is useful to make sure we're not just being fed feel-good make-believe.
And before everyone gets upset, tax serves two purposes; 1) control inflation (it in effect burns money that was issued when the govt previously paid for things), 2) disincentivises selected behaviours. and one side effect, when the govt runs a tax deficit it increases inflation, and of course the contrapositive is also true.
