Whenever I read statements like that, it's as if somehow the EU/US think they have a right to be the dominant global economic and political power, and somehow it's their moral right to stop anyone else from ascending to that position.
China has over a billion people. So does India, so does the continent of Africa. They are all developing much, much faster than the vast majority of people realize 
Anyone who thinks the EU/US will remain the dominant global economic and political power in the next decades is severely deluded.
 Checkout the fantastic "Factfulness: Ten Reasons We're Wrong About the World--and Why Things Are Better Than You Think " by the master Hans Rosling, where he clearly demonstrates using irrefutable stats that the poorest countries in the world today are developing faster than for example Sweden ever did, at any point in history. https://amzn.to/2CXPdCu
The world is a lot different than many people think.
I highly recommend it.
