All of Russia hates Moscow. Not because the people there are bad, but because 65% of the income from each region goes there. The areas outside the Moscow Ring Road are all colonies of Moscow, which drains their resources. As a result, the standard of living in Moscow is much higher, and everyone wants to move there. Whose merit is this? Maybe it's the State Department or the Freemasons?))
This is not hatred, but hierarchical relationships, which any society is built upon. Of course, there are frictions between the levels of the hierarchy, and there cannot be any without them. These frictions are especially amplified by people who believe they deserve to be on a higher level than they are.
Specifically, in the case of Russia, it has turned out that both the administrative and financial center are located in Moscow. In some other places, it is different; in the United States, for example, the administrative center is Washington, and the financial center is New York. And there is also a possible (and in many places partially implemented) situation where the administrative and financial centers are separated not territorially, but by clans.
I think that over time, the Kremlin will realize that it is better to redistribute Moscow, to move a number of government and financial institutions outside of it. This is organizationally more complex, but politically and economically more beneficial.
