I am thinking this is more how the conversation went down. She inquired and they said she probably would not get roles without paying, given her inexperience. I do not think this rule applies to primas, but to those who just want buy a role even if they are not ready.
I am confused as to why at 19 she would think she would get solos. Absent a few prodigies like Smirnova and Vishneva, very few dancers start out with solos in their teens in ANY company, let alone a great one with 200+ dancers. Perhaps the comment was just the straw that broke the camel's back and her leaving was a long time coming.
I hate to make a sports analogy, but this reminds me of Tim Tebow, an American Football player. An athlete that does well in school, but not in the pros. When in school, he only has to compete with the best school-aged players. In the pros, he has to compete with all athletes that were the best of their schools.
Every person in the Bolshoi, even the lowest corps member, was the top of his or her graduating class. Now she has to compete with 100 female versions of herself, some who have been dancing with the Bolshoi and improving for 10 years or more. She may have had her confidence built up too much in school and not realized this.
That sounds facile.
A lot of people are creating a lot of negative push back against girls who allegedly complain or quit based on this appearance of impatience for undeserved or unearned solo roles. I really doubt that happened. Certainly, the news and gossipy boards love to talk about it. Marketable armchair psychology. The publicity machine thereby accomplishes its mission, I guess.
You would be disillusioned, at the least, if you had been young, idealistic, naive, trusting, passionate, a perfectionist, devoted to creating art and beauty, taught to be an obedient follower, far away from home, and then came to a hostile environment in which you learned about and/or experienced, claques, acid attacks, threats, hacking, defamation, circulation of false emails and facebook hacks, unfair labor practices, nonpayment, breach of contract, breach of trust, glass in your toe shoes, political influence, improper treatment of respected artists, disloyalty, gamesmanship, forced abandonment of a teacher and star not currently in power, sexual favors with patrons and possibly others, infighting, and how the game is played through the making of payments. All while you were worrying about money you had not been paid and while you were starving and aching and exhausted, physically and emotionally, from working all day.
But I guess it is easier or more useful to say she was greedy and aggressive and a small fish in a big pond.
