Here's a text from a French PhD candidate, user of the app: " [1] Thanks for the advices. I still believe that leveling up your looks and habits can help with becoming affluent. Or at least they are also an important aspect... [2] I believe I got the impression that some wealthy men don't care about woman's work or career...".
My first observation is that a PhD candidate is not a PhD. The degree of a PhD candidate is the Master degree. This confusion is recurrent. In France you might be able to register for a thesis when you have a Master degree, but the title of "Docteur" must be earned with a concrete thesis, which supposes many years of work and sacrifices. Only 10% from the people registered at the Sorbonne University, for exemple, as PhD candidates, go to the end of the process, by defending the thesis in front of a jury and the public ("la soutenance de thèse"). More than an intellectual test, a PhD is a psychological endurance test, many do not resist at the pressure.
She is right when she says that leveling up your looks and habits can help but Anna Bey is not a model in the matter. She looks like a hooker and have very debatable habits. At a higher level job, the duty of representation is high. As
@MollyHL said it, you might have some succes with your looks, but if you don't have the capacity to talk about many topics, in a credible manner, you can't survive. Coupled with the fact that the degree in a given field does not help you in another field. In order to hit the attention of the high society and wealthy men it requires a constant auto-training (to acquire a general culture, to understand political issues, etc.). This become natural for someone with degrees. Contrary to what we might think, because the stereotype is to say that a good society don't speak about Politics or Religion, 80% of the discussions are Politics and Religion, the rest is Arts. Lina Hadid with her "Free Palestina" plastered on her bags could be seen as a child but actually nobody knows her in the high society of Geneva (here you have a hint from the inside). The situation Israel/Gaza strip is more complex than slogans and you have to be able to discuss with Zionists and anti-Zionists (bankers, diplomats, etc.) at the same level of knowledge and undestanding. Religion is the same. Many men in the aristocracy are knights of the Order of Malta (very religious) and many men from the haute-bourgeoisie are in the Freemasonry (anti-religious). They get along very well because it's another level than "this is good/this is bad".
I've already made a post about her n° 2, this is a wrong idea or maybe available for old people. Wealthy men and high caliber men need intelligent women that take all the light in society, at a dinner, etc. And I am not talking about their dresses and make up. An intelligent and cultivate woman can make the career of her husband, a superficial one can destroys him, the perfect exemple being Anna Bey who isn't even invited by her own
husband in professional related gatherings. The new generation of wealthy men, they are proud when their partners have a successful job and are able to entertain in the same time a duchess with a fancy dinner. Social skills in this particular society requiers more than good looking girls with Hermes bags. As always, when I speak about the "high society" I am talking about the real one not the Instagram "good society".
PS. Oh, important observation : one doesn't really need a PhD to have succes in life
You can also have access to all of her private and personal info just if you know the right person working for the gouvernement (I do)
