Hypothetically, a global government could re-allocate, much as a federal or central government now does to help regions/provinces/states. It could also regulate global markets, address climate change, fight Ebola, etc.
Here at the G20 summit, leaders representing 85% of world GDP are meeting in Brisbane, Australia.
It’s not just the G20 group of world leaders who are meeting. Also here are the heads of the International Monetary Fund and World Bank. There’s also the associated organisations, such as the B20 (business), C20 (civil society), L20 (labour), T20 (think tanks), and Y20 (youth).
