again some baseless illogical reasoning. elaborate why you think that the EUs % of global GDP has anything to do with brexit. i see no connection here.
and btw, of course the EU is a shrinking percentage of global gdp. its much more profitable for people to invest their money in less developed faster growing economies. you get a bigger return there. what you need to look at is who actually owns the capital. not what country its in. its the 21st century.
why do you think that deregulation, less oversight, less, and more expensive, trade with the mainland, less investment in smaller european economies, will be good on the long term? i think its bad short term and bad long term. what mechanism do you think exists that will turn things around? what will change in a few years? how long is short term anyway?
