Are men threatened by successful women?

In Chinese folklore, girls born in Tiger years seem to be cursed. They bring bad luck upon themselves, to their families and even to their husbands' families.

I, as a "tiger girl", am a little bit offended by this. Though I don't believe the old sayings, I could not stop wondering why the Chinese ancestors had such hateful thoughts for tiger girls thousands of years ago. Then, I read a theory about "surplus women", referring to those who were approaching their 30s.

In the theory, all men and women are classified into four categories: A, B, C and D from the elite class to the bottom class. And it works like this: A class men marry B class women, B class men stay with C class women, then C class men choose D class women.
