*Aprilrose" The world is getting smaller on a daily basis. The most powerful organisations are the multinational corporations who manage to pay less tax because they are able to make use of the various tax havens.
Whilst during the 19th century Britain controlled the largest empire in the world we are no longer in that position and we can never get back to that. We are now the 5th/6th richest country, possibly soon to be 7th. However, much of the wealth has disappeared off shore. When the UK is rated by GDP per capita we are 23rd in the list, below most of the other European countries, including France and Germany.
As as been said in several threads, new EU rules that affect the taxation of multinationals and tax havens are operational from next January and that is why Johnson is in such a rush to exit on 31 October.
