Marxist-Leninist Philosophy was a required course for all undergrads in my time studying in USSR. Strangely enough, the professors made it into an overview course on history of philosophy, which was quite enjoyable, with just some mention of Marxism-Leninism in the last lecture.
What in some countries is grad studies, is in other places undergrad, and in a personal high point, high school extension studies. In contemporary rich country education systems, it’s not just grade inflation, it’s very low expectations of the student population’s capabilities, in my opinion.
I'm from such a country and this tracks. I often look to individuals of the past with the same academic credentials as me and it seems they are much better read & educated. And when I was in school, it often felt like my education was diluted to cater to the LCD.
