Today the USA, China, and Europe divvy the world up and own about one third of it each. In 30 years, things will change and Europe will decline and be weaker. Demographic growth - the main cause of economic development - will highly increase only in Africa, but there, economic growth will be irrelevant. Therefore, world development will be stuck, as it will grow little. This century is going to drastically change the world. Not only economic development will be blocked, but we are going to live the new Cold War between the USA and China, the migration tensions, a greater poverty and inequality, a technological revolution, an endless urbanization, a changing work, people getting older, a crazy climate and a broken middle class. The hegemonic strategy of China - which will start to abandon Africa - will try to take pieces away from Europe in the name of the Eurasia dream, while the USA will try to create troubles to Europe with their is.
