“Complex, but right”. Some of us have known this for a long time. Recently here in UK and in the USA too, the “simple but wrong” line has won the day, but I feel now that its day has passed and that slowly, even those who are not great at thinking are beginning to realise that something somewhere isn’t right. That does not necessarily mean that they will plump for the more complex solution, but we may yet see a few apple carts taking a nasty toss. Let us hope that not too many people get hurt in the upsets.
