Nah, they won't kill everybody. They will, however, find a place far from here so that they can separate themselves from us and live as a utopia of 'perfect' people. In that way they'll have their ideal home for the "elite".
The lower trash is needed to keep currency relevant and for them to keep their sense of superiority. Otherwise they'd become the very thing they hate after some time and will start that wheel all over again.
It is true that we're being exploited, though, but just not to die for them but to build their 'utopia' for them, along with their food and shits that they want and need.
