Has to do with how people in the east are basically being dragged behind by the west. They are getting paid less, but have to pay the same amount as westerners for electricity, gas, water, internet, and everything else except for rent and sometimes food.
A lot of the folks I talk to remember how the "west" turned the previously state owned railway company into a private company which caused almost ~75% of the at that point running rail network to be shut down for profit reasons.
People are upset, nothing is being done, they are being fed propaganda, and the results can be seen as clear as day
