Divide & Conquer.
The more the bribers can keep the American public divided the more control they have over us. They want Americans fighting over what is right and what is wrong, what is good and what is bad; this distracts us from the corruption this is really going on. It is to the benefit of the bribers. They do not want a unified America because then they would lose all power.
The Media doesn't talk about the most important issues facing the country, because that is not what the Bribe System establishment is paying for. The more the people fight among themselves the easier it is for them to distract and make more money.
The middle-class demise has been happening in the United States pretty aggressively since the 1980s, since the Reagan Revolution. As the middle class has gotten wiped out by Reaganomics. Fifty trillion dollars have flowed to the top 1% from the Middle Class. People are losing their lives. Losing their economic livelihood. Losing their families. Losing their income. Losing everything. People work two jobs just to make ends meet. They thought back in the eighties that they would be doing better than their parents, and now they're doing worse. Their children are doing worse than they are. So what do they do? They turn to violence. They listen to right-wingers who tell them; it's because black people are taking what they deserve. Or it's because of those immigrants flooding across the border with their hordes of children. We need a wall to stop them. They don't realize that a wall is a scapegoat to fool them. They don't realize that they've been screwed by Reagan and the Republican neoliberal policies of the last 40 years. So then come along demagogues saying “the government is still trying to control you.” It's not the fault of the Republicans that you're broke. It's not the fault of the 1% rich in the United States who have become richer by stealing from the Middle Class. They tell you it's the government bureaucrats who are trying to sedate you and keep you down when in reality it is the Bribers who are doing it. The more atomized and unhappy American society becomes the easier it is for them to control.
Information has become a partisan issue. It's the classic dictator/authoritarian ruse to accuse the other guy of exactly what you are doing, and when the other guy accuses you of something. you call it propaganda. That's why the word disinformation itself has become problematic. People on the right believe that the big lie is a partisan issue, so when the big lie is discussed they scoff it off as just another partisan issue. It's easy to rally around disinformation because one man's disinformation could be another man's truth. We see it all the time now.
There is only one truth. Part of the problem is that the side with the truth and the facts want to meet the Liars halfway. There is no halfway point between the truth and a lie. Are there two sides to a lie? When one person tells the truth and the other tells a lie you have to be able to distinguish between the two. Democracies don't function without a shared set of facts. If you don't agree on a shared set of facts then you can destroy democracy.
