In the USSR, nominally and "indicatively" women had the same "rights" as men. But besides the fact that in the USSR people did not have rights, there was always a rather arrogant attitude towards women. No, of course there were women - "exhibition specimens", but in 99% of cases, they were citizens who were rather limited in their abilities. All this was based on a historical "habit" that a woman is, at best, a housewife and nothing more. In the USSR, they tried to show that they had already got rid of the "tired legacy of the tsarist regime", but it turned out extremely badly ... Where women succeeded as much as possible " realize themselves" and reach some heights - there were purely humanitarian areas - kindergartens, schools, hospitals. And then with reservations. And these complexes remained even among those who were born in the 70s+.
This situation is not only limited to a specific period in the history of Russia (the Soviet Union), but even in our present era, and in the most advanced countries, you will not find that the number of women in business exceeds the number of men, even if the proportion of women in the population is the largest.
It is not only limited to determining the role of women in the affairs of the home and family. There are many areas in which we almost never find women. For example, the building and construction sector has no women investors at all, as well as mining and the production of solid materials. These are all sectors in which women have no luck without a valid reason.
