UNITED KINGDOM REENGINEERING The UNITED KINGDOM gains between 800 AND 1700 TRILLION POUNDS, over the next century, in inflation adjusted GDP, if the UK adopts PCT and CTS, according to grok 4. The range is from three runs of grok 4, which predicted .8 QUADRILLION POUNDS, 1.1 QUADRILLION POUNDS and 1.7 QUADRILLION POUNDS, respectively. These are the three grok runs: x.com/i/grok/share/G2MNrpVKM… x.com/i/grok/share/Pqjg18r44… x.com/i/grok/share/g3eg4jupV… PCT is an elegant progressive consumption tax only paid by the top forty percent of workers. The bottom sixty percent of workers pay nothing. All other national taxes are abolished. CTS is similar to tariffs but far better. It ignores actual trade and focuses on international capital flows, securitising them in a way that directly buttresses domestic production while disadvantaging imports, all with no cost to the treasury. Both PCT and CTS are defined in the paper in the first comment. Grok used this paper to answer the questions. The surprisingly large effect is the result of small annual gains compounded over a century. The range in estimates is due to a variation in the prediction of the small annual gains. So far all AI have predicted very large virtuous effects from these two simple changes. I encourage the reader to try their own AI or an open minded economist. The main point of this post is to emphasize that all estimates suggest a great positive effect. Precise predictions are impossible with chaotic systems, like economies. The important takeaway, besides the value of these two changes, is that we should conduct our affairs in a manner that optimizes GDP growth, because it has very beneficial long term effects. It is quite possible that our economy would be much larger if these two changes were made decades ago. ( On an unrelated but important note, I would like to add that even though I basically just sit around reading and trying to think of ways to make the world better, I was, surprisingly, secretly slandered by a USA stalk racket and those they paid well for the slander. The stalk racket has been following and poisoning me for over 28 years, with the full knowledge of the government and police, who feign ignorance, ignore complaints and arrest nobody. Is this the freedom and liberty so loudly advertised? The refusal of my government to do its job is infuriating. )
