Well, the EU is going to explode. The currency union aspect of it was never a good idea in the first place. It's a matter of when not if that happens.

By contrast, in the US I think it is a matter of if not when we will ever see a return to historic "normal" interest rates (about 5%). The Modern Keynesians are really about to break through into the mainstream. And they maybe onto something about the old monetary indicators being inappropriate for the modern economy. After all, if we're looking for price inflation to be the tail that wags the dog, there are a lot of good reasons that have cropped up in the 21st century for that to have stopped being a reliable indicator, among them globalization and the digital sharing economy.

In China, it's a race between rising debt and sovereign investments. There's a chance that all the infrastructure building that the Chinese have engaged in will grab them a share of that seignorage that allows the US to print money so freely without consequence. For now, China is relying on its planned economy to hold things together and they are hoping that will hold until everything that is the One Belt One Road matures and can contribute significantly to their economy. That's a big bet. But they probably have the best leadership out of the 3 regions mentioned here.

That's my view @crypto.piotr, thanks for asking!
