The main plot of the episode was that Cartman was sent to a universe where he was transformed into a powerful, capable brown woman of color but who talked exactly like him. A bunch of commentary on movies, studios and franchises that reinvent characters for ESG scores.
The B plot about the lack of value of higher education and white collar work was main plot worthy and I wish it was the main story.
South Park Studios dribbles out specials now instead of seasons. I guess the creative juice has to build up (unnecessary metaphors and comparisons omitted.)
