What keeps that from happening is the elites know the pie is much bigger in western countries that have an illusion of freedom.

There is very little room at the top in China and even less as freedom gets squeezed harder an harder and absolute isolation is increased like in North Korea.

If the west were to give up their illusion of freedom it would be the result of a faction war amongst the elites. Most of them may be power hungry and amoral but, so far, I haven't seen evidence they are ideologically driven. That is what they use to manipulate the masses.
