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.

I think China is the only real contender for the next superpower, I mean until the last 500 years they were arguably the most advanced country on the world. I think they have been held back by the government's consistent purges against intellectuals, and this will effect China's chance to grow now politically and economically.

India has too low an IQ to be a world superpower. The eastern asian countries are only growing fast economically because all the technology and knowledge is already in place for them to do so, at best they will catch up the west, but I doubt they have the innovation to take over from the usa or europe. The huge popultion of China however will give it more influence even if they dont achieve the standard of living in the west.

The downfall of the USA and europe will be immigration, and low white birth rate, but still I see them holding onto their position a superpowers for the next 20 years at least.
