Instead of having a world-wide federation, we will most probably have a period of dissonance around the nations where people will close more and more inside their borders, until they feel they have the power of their lives in their hands again.
I know you won't like it, but I will blame unregulated capitalism for this one. Media is so sensational, because they know nobody will watch / read anything that has a boring title. Social networks are becoming click-junky. Advertisement is fraudulent on a lot of levels. Globalization, instead of making poorest people not so poor has made rich people richer and so on. And no wonder this tendency is going worse with such a high-priced education.
