Horse shit.
The American government is and has always been an oligarchy, with brief periods of time in between intensifying authoritarianism where the people managed to catch some extra bread crumbs with enough push back.
This is like condemning the people of other authoritarian countries for the actions of a government that actively enslaves them as well. Fucking moron tankie ass type of take.
That Carlin quote is less relevant now than it was when he made it. The people have never had less of a say in US politics before the Voting Rights Act, which was repealed recently by SCOUTS that is rewriting the constitution as it goes.
