As an example we can take Finland that has an obvious area more dark in the east than rest of the country. The funny thing is this area delineates a territory that fell under the Novgorod sphere of influence in 14th century in the treaty of Nöteborg https://en.wikipedia.org/wiki/Treaty_of_N%C3%B6teborg

When people are forced out of their social and economic agency by a narrow elite, they will continue to be deprived of their agency long after that elite is replaced by another elite and another elite until people forget that they ever had culture and wealth. Now, I don’t think we’re seeing the worst manifestation of that in the U.S. Far from it. But it was striking to see not only how consistently problematic elite stratification is, but how good it can be to give power to the people.
