Actually there is (or at least use to be) an idea of "progress". The hope was that people in the predominantly Russian-speaking Eastern regions would eventually "convert" politically to a pro-European direction because a primary driver of the pro-Russian leanings (other than cultural factors) was a positive memory of industrialization by the USSR which brought them jobs and a better way of life. The idea was that the older generation who remembered the glory of the USSR would eventually become replaced with a less Russia-centric one. Unfortunately this hasn't exactly played out to the extent it was hoped for.
