I am not sure if you are being patronizing or condescending.
Both; it's a thing between John and I; he does it to me all the time, and I occasionally do it back.
However it would appear that your signature is in conflict with your hypothesis that experts are just "sticking fingers in the air"
If you actually read my signature properly, you'll find it read "if at first you don't succeed, find someone who knows more than you do", says nothing about experts, so why are you conflating the issues.
It is now reckoned that the BoE's decision to reduce interest rates was just an unnecessary knee jerk reaction, and may well have made matters worse.
The government has not explained what Brexit means, because it's a negotiating process. If you tell the other side what you want straight away, they know where your weak points are.
Market forces didn't intervene to avoid negative economic results; the exchange rate drop was a panic reaction by the markets, and exactly what the government wanted to happen, because the pound was overvalued.
Thus, rather than decrying the economists predictions and policies, we should be lauding them for their foresight and courage in implementing policies to avoid their own dire predictions.
I'm not sure if you realise just how much of a contradiction this is. The dire prediction were designed to make use vote differently, they weren't intended as policy to determine a course for the future. As their predictions didn't come true, then their so called expert status can be called into question. George Osborne was fired by TM, so didn't implement anything, and neither has Hammond, so no policies have been put in place to counter the decision to leave the EU, yet we are stronger now than before the vote. And yes, as Noseall always states, we haven't yet left, and there will rough times ahead, bu none of the predictions to date have come to fruition, and no plicices have been implemented that would explain the current economic situation.
We can all do that, without years of education. In my experience education is a fundamental process of avoiding mistakes
Unfortunately, history tends to show that we don't learn from our mistakes, and continue to make the same ones time and again. Very few poiticians stay in office long enogh to learn from their mistakes, even if they were able to.
