Outside Moscow, salaries are many times lower. That is true. But you have to remember that everyone in the regions has a vegetable garden and a plot of land. People from the regions eat from their gardens, raise poultry and cattle. So they only need money for clothes and utilities. So it is fair that their salaries are lower than in the capital, where they have to buy food, among other things. People work hard in the capital, the pace of life is crazy. In fact, Moscow supplies the whole country with resources, attracts foreign money and provides the regions with jobs, so its residents need a good, expensive holiday.
