In America, The System Says Roosevelt Is The Emperor

I just traveled to another world and was in the United States, but the system said that I had arrived in the Warhammer world.
The homeless people on the street are called bottom-nest rats, the cows and horses working overtime day and night in the factory are called bottom-nest coolies, and the congressmen are called the nobles in the upper-nest spire.
I can barely understand the above, but can anyone explain to me how Roosevelt’s speech, which is clearly playing on the radio, has become the emperor’s teachings?
Is it possible that one of them is sitting on a golden toilet and the other is in a wheelchair?

President Roosevelt, no, no, no, Emperor Luo, you are the greatest emperor!
For the Emperor!
