China is far from perfect but based on any fair reading of the evidence I would much rather be in their position than America's.
Basically, I wouldn't vote far, there's a lot of hate built up in America because a lot of problems have been procrastinated or neglected. The economy is not doing so well and Trump is playing hardball. The only question is how resolutely others will react to his hard power and his intimidation. Even if it is not sold that way, America benefits indirectly from wars.
China's problem lies more in the population, which is why it can be monitored almost continuously, and the problem here also lies in the lack of good jobs for the educated class. China is pumping a lot into the economy, but Europe and America can't take enough. China is also trying to take over territories to keep the defense line away from the mainland.
Russia is struggling with its position and cannot cope with the political downturn and that China is now much more influential than they are, and former vassals are much more demanding where they used to be supplicants.
Europe cannot find a common line and loses itself in itself, the interests are broadly diversified and it does not quite know what it should be, a big player on the world stage or just a junior partner of America, which problem becomes more obvious in Great Britain, which is still struggling with its loss of power on the world stage and the disintegration of the great empire, but could do Europe good, but is too proud to do so because it wants to decide alone.
Africa is getting lost in the warlords' petty wars and cannot find common ground to gain its own strength and the governments want to enrich themselves instead of putting a common Africa on its feet.
We are not necessarily in an economic crisis, but rather in a turnaround whose first traits may already lie in the First World War with the collapse of European monarchies, the exasperation of Germany due to the imposed excessive reperations that, as a part, led to the Second World War. The struggle for supremacy between the powers USA and the USSR and the imperialist world police representation of America (which is now becoming too much for them). The transition to a war of faith against America and the West, and to some extent Russia, plus the formation of a united Europe.
There may be a battle over who determines the near future, but it is also possible that the current structures will collapse into something else. I don't have a crystal ball as to where all this will lead us, but the course is being set.
Europe has partly recognized the signs and is forming something very special. Founding a confederation of states without everyone speaking the same language is something very special, the idea is great and fascinating. But Europe doesn't know what it wants to be, does it want to grow even closer together and merge or remain as it is. But it has recognized that individual states are no solution. How great it would be if the dream of a common Europe became a dream of a common world...
All empires have disappeared at some point, it may be that the empire of capitalism is crumbling and climate change is an accelerant of this.
