The world in 2057

Is it possible that USA is on a slowly descending course and will be replaced with EU as the next leading super power? I see three alarming tendencies:

1) Protectionism. Not only is it bad for the economy, it also breeds mental isolationanism.

2) Xenophobia. If you got rid of all illegal immigrants working in "the breadbasket" and enforced zero tolerance against anyone trying to enter the country illegally, even to make a honest living, then the food prices would skyrocket.

3) Theocracy. If you want to have a separation of state and church, then you must keep them separated.

If USA isn't breaking these tendecies like right now, then it's doomed. My guess is that in 2057 is EU a superpower far more powerful than anyone could've imagined. It rose to superpower status during the colonial wars in China on african soil. EU is allied with the African Union and are trying to contain the threat from the pan asian coalition headed by Russia and China.

The EU together with the US is 60 % of the world economy in some aspects, and the US invested 4 times as much capital in Germany as in China the previous year.

Yet, Europe barely has the potential to take #1, and is definetely to weak on critical issues to take over, lest it does some serious catharsis or, preferably, bites the bullet and reforms NAO!

China... I'm not sure about China, economically or politically, but I am interested in India and Brasil. Russia can rot for all I care - the only productive citizens are muslims and everybody treats them like those from the Caucasus.
