There's this line from the movie “Platoon” (an American movie about the the Vietnam War), where the character “King” said…
“the poor are always getting fucked over over by the rich, always have, always will.”

Once the rich accumulate money, they want to accumulate more money by setting up the system to make them more rich, like you said. If the poor and middle-class understood how the rich did this, they would be less inclined to take out debt and give more money to the rich.
