I have provided calculations and data and the sources of my data.
You have as yet still provided us with no explanation of your assertion that means testing is “cheap and simple” which contradicts all of the data I have provided. You demanded sources from me, but have provided no data or sources whatsoever to back up your assertion. Why is that?
You have said you think the figures I provided are wrong, but haven’t said which ones are wrong, or provided your evidence and sources for this. Where are they? Where is the data to support your assertions that contradicts the data from the NAO, the OBR, the ONS. I’m not going to post links to the specific pages from which each figure is available because Google exists and you’re not paying me for my time.
Then there is the independent economic research I referenced which are all publicly available for you to look at? There is also research on this from Loughborough University, King’s College London, and many others, on the economic effects of cliff-edges created by means-testing taxes and benefits. Just a few examples below. Since you delared you know nothing about economics, for a very simplistic visual demonstration of the absurd effects the final link may be particularly useful:
King’s: kclpure.kcl.ac.uk/portal/en/publications/the-impact-of-income-tax-changes-on-government-revenue-moving-bey
A simple article on some other studies e.g. Loughborough: https://theconversation.com/how-cuts-to-marginal-income-tax-could-boost-the-uks-stagnant-economic-growth-226758
Several graphs showing the effects of means testing various services/ benefits, precisely what recent universal credit reforms are aiming to remove in one specific case but many more remain, distorting economic activity and reducing economic activity and growth, lowering tax revenues and creating skills shortages: taxpolicy.org.uk/2024/10/17/reform-income-tax-end-the-scandal-of-high-marginal-rates/
I’ve tried to keep it simple for you with accessible articles summarising some of the simpler studies that aren’t too mathematical and complex in technical detail since you stated you’re not knowledgeable about this area, but high quality and evidenced articles referring to their sources. There are many, many more technical papers studying similar phenomena in multiple different countries which is why most comparable developed countries do not adopt such an approach because - lucky for them - they largely have competent politicians who tend to make evidence-based policy decisions.
Now, I’ve wasted a great deal of my time on this and tolerated you insulting my professional competence. Are you going to explain before the thread gets full and provide any calculations, evidence or data sources supporting your assertion that cheap and simple means-testing of PIP can be implemented and explain how this will be achieved, how the IT issues can be resolved without this costing tens of billions of pounds? Presumabliy you have got some data on what the cost would be if you think that I am wrong, and the DWP and HMRC are wrong and the ONS is wrong, as are all of these economists who have made clear that on top of the costs to Government there would be economic costs several of orders of magnitude higher, vastly outweighing any savings, as is the case for the current cliff edges that exist per the data?
You keep demanding more data from me when I’ve given you calculations, data, sources and detailed explanations but you have made assertions here for which you have provided not one of the above at all.
I won’t hold my breath.
