Your favorite opera about cossack oppressors being banned? From that list egregious things are A) not teaching in schools/then in 70s making salaries higher for russian language teachers (time doesn’t make sense in that sequence, but whatevs) B)making dissertations in russian/ I assume not all national arts were some glorification of oppressor class
Thus we arrive at meh about language being banned, but solidly yes at it wasn’t encouraged/developed.
My great grandma lived through 30s-60s, spoke ukrainian for whatever it worth her whole life, was a math teacher if I remember correctly (don’t know what she taught it in, can ask relatives sometime)
And simultaneously with this crusade against white cishet mindset, you delete poverty finance.
Really do be feeling that downwardly-mobile professional class tbh
