Yes, we have a clear exploitation of the eternal division into the poor and the rich and the production of hatred from the poor to the rich and aristocratic. Besides our world is so organized and people tend to hate someone. And who it will be, red-haired (in the Middle Ages), beautiful women, who were simply burned at the fires of the Inquisition, believing that they were witches or our beautiful and bitchy Monica Buckfett, is not so important. Social and financial division of people has not been overcome, so we have what we have. And your point about protective alliances makes sense too.
In general, though, this whole situation of trying to generate hatred for rich Monica reminds me a lot of a funny song in Russian "A woman in a Lexus" by Semyon Slepakov.
You can turn on subtitles with English translation (settings->subtitles->translate->English), but if something will be unclear (google translation is not a model for imitation),
(below is a more literary translation of the whole text).
I'm sure if our Monica was a "poor bitchy girl", this effect of the game just wouldn't be there.
Thanks for your review, read with interest and generally agree with what you wrote. As for Biff and Victoria, well, let's hope for that outcome. Although Victoria could serve as Monica's personal pet, and if "Miss Skinny Ass" misbehaves, she can always be sent to the Farm.
