Yes, that’s true: the methods of oppression in the U.S. are still relatively subtle at the moment. However, that doesn’t change the fact that in the U.S., too, a tiny elite exploits the country while standing above the law - a point proven by the very fact that the current president is, in fact, president rather than serving a life sentence in prison.
What I’m getting at is this: It would be easier for this elite to switch to the Russian model. I consider it likely that they intend to do so, since the current regime demonstrates on a daily basis that the most serious crimes in the US always go unpunished - so why even maintain the facade when it’s already abundantly clear that the law simply doesn’t apply to the powerful elite?
