When I started to study Russian, I read one or two of his stories in this book [1], which was great because it has English and Russian versions on opposite pages. I got to enjoy reading in Russian because I didn't constantly have to look up every tenth word in a dictionary.
Russian is a hard language but there are some still harder. To understand magazine articles and carry on simple conversations on arbitrary topics is a time investment of about 600 hours. To read Chekhov and speak really well on advanced topics is about double that, or 1200 hours. Chekhov's style is close to modern Russian and his style of writing is more straightforward than earlier writers. To read Dostoyevsky... well, hell if I know, I can barely make it through the first page of Crime and Punishment even with a dictionary even after all this time investment and living in Russia for a few years! It's like a different language.

Chekhov is still tout in Russian school : https://ru.wikisource.org/wiki/%D0%92%D0%B8%D0%BA%D0%B8%D1%8...
Only in the later stages of decline, when economy was tanking and people spent half their time queuing for things, they probably had less time to read...
That's what I meant: in the turmoil of 1991 and beyond, people would have less time to read...
However I was thinking already 1980's: probably the dysfunction of the economy had an impact on people people's reading (like, do you typically read a book while you are at the meat shop queue or shoe shop queue?)
