Except it isn't growth. Zoey partying too much and getting cut off is fine. Zoey was doing well academically in college. It was only because she dropped one of her classes mid-semester that she needed to do well in chemistry to maintain her GPA.
However having her turn her nose up at getting a job and overemphasizing her self involvement, while her vapid friends lecture her, is terrible writing. Especially when there is a much more complex, and interesting, character arc to be mined, that doesn't involve the usual Black-ish/Grown-ish verse misogyny.
