The US Establishment has a lot of power. I believe you are right that they are starting to lose a grip on this power. This is mostly in regards to political power. Big businesses can partially escape this downfall because they operate globally. They can thrive through alternative hubs. I think we can see this with the rise of global organisations, which are supported by almost all the largest companies in the world. The WEF are strongly promoting the centralistion of power. This power would not necessarily sit strongly with the US Establishment political parties. The world is very likely to go through great changes over the next decade. It is a great opportunity for people to break from the system but things could also go horribly wrong.
