Ruling The World In 2050

PriceWaterhouseCooper (PWC) are one of the big four financial auditors and they have been looking into their crystal ball to see who will be the economies that matter in the year 2050.
ALl the usual suspects are there but the G20 summits may have to swap around some of the little nation flags they put out at the lunch tables because according tp PWC, there are going to be some changes over the next 30 years.
Of the current G20, they can keep most of the flags but being ripped up and turned into dusters are the flags of Australia, Spain, Canada and Italy and in their place being hoisted up the flagpole are the bits of cloth showing the colours of Egypt, Philippines, Nigeria and Pakistan.
Gaining an invite to a G20 summit means you are one of the biggest and best in the World but when you get an invite for the G7, then you know you have really made it and as one of the most advanced economies, you get to make the economic decisions that effect the rest of the World and currently the Group of Seven consisting of Canada, France, Germany, Italy, Japan, the United Kingdom, and the United States but some of the leaders better make the most of the Foie Gras on offer as not all of those nations will still be tasting goose liver in 2050.
Of the current G7 countries, Russia (if still not banned) will be there as will the USA and China but France will be replaced by Mexico, Germany booted out for Brazil, Canada hooked in favour of Indonesia and Italian meatballs will be off the menu and Indian Curry put on it.
The auditors include a disclaimer that this is based on current projections and things could change between now and 2050 but they have the UK economy slipping down to 10th and China being the largest with the USA 3rd and India 2nd with the biggest movers upwards being Pakistan and Nigeria and biggest drop coming with the Japanese and South Korean economies.
