This mainly has to do with western women not being as a good looking as eastern women on average , so they get more attention on average than western women
then the western guy being a simp starts worshiping the EE woman , and in return she becomes like the western woman or worse ( mainly because they due to their better looks )
The actual process is this one:
Natalia moves from Poznan to London, she realize from the moment of her landing that all the men look at her as if she is a top model, she no longer has to carefully decided what to bring and what not cause random men will move her lullage regardless for her, she wont have to ask either cause they will offer themselves.
She also doesnt need the full amount of money needed for that cheesburger cause they guy that approaced her is more than glad to pay for it especially after she didnt treat him like crap when he approached her despite she didnt find him attractive.
Day after day she sees annoying dumb girls, fatter and louder than her being worshipped and chased while none of that happened her whole life in poland...she didnt have crying as a way out of bad homeworks and teachers punished her wrongdoing like everybody else.
The guys she date now are all in the top looks range and no matter what, they never complain or give her negative reinforcements when she is late or annoying.
After few months of this she not only believe she deserve stuff cause she is special but she has to get back for all the special treatment she didnt get at home, she actually think at home she was mistreated given the new reality.
Yet she is not as stupid as the average western girl, so she wont cut her hair short nor get too fat while keeping b1tchy behaviour under control cause at least there is one thing she remembers from what her grandma said: "dont wait too much to settle cause no one commits to old women".
