[BobaFloutist]

I don't really feel the need to specify which powerful people that have extensive financial interests in exploiting nations are or are not particularly loyal to one nation in particular, but I guess you could go with "rootless cosmopolitan elites", "smirking merchants", or even just "The Illuminati".

If you're referring to a specific, discrete group of people, you could just name them instead of using a laundry list of questionable adjectives. But that wouldn't imply a global cabal, and so you couldn't oh so subtly and inconspicuously point fingers at an ethnic and religious minority.
