Two brands of lunacy -
1. What could possibly go wrong?
2. On Brexit, why are the politicians so scared of 'no deal' why can they not walk away? If we had a Trump over here that is exactly what he would have done. I think the answer is that our politicians genuinely have no idea about the realities of commerce, about business but also they have no confidence in the British people's ability to resove problems or to come up with imaginative solutions, despite all the evidence. A recent example was Danny Boyle speaking on a TV programme about his 2012 Olympic show. He said they spent ages trying to get the lighting right and properly sequenced. All of his set designers and experts were stumped by it but when the lighting riggers and electricians worked it out and did it for him he was amazed: 'But they are just ignorant peasants with no education' - that was not what he said but it was clearly in his mind because he did not have the creative imagination to solve problems and they did. (I have seen that countless times with architects)
Any problems with 'climate change' or caused by Brexit can and will be overcome by the remnants of our industrial heritage and our make-do-and-mend approach. Unfortunately such things have been educated out of us over recent years. I have mentioned that before in a post but can't remember which one :)
