If you observe carefully, most Karens were very beautiful a few decades ago. They dress well, they keep their hair good (the Karen hairstyle was very good a while ago), they are educated and they use sophisticated words... they just are nasty people now.

The amazing things is that Karens still have more privilege than any average man. Yes, some men f*ck anything, so those women still have plenty of options to pick. Plenty of them are married and divorced multiple times.

However, after Karens being in the top of attraction in your youth, and seeing how even a common McDonalds female worker get more attention than her. No wonder she gets angry against service workers. It is the same phenomenon as alpha widows. They cannot accept their top days are over, they cannot accept attraction can be lost (even if it is just like 30%).

Men cannot be really angry without serious legal or social consequences. Most men also eventually accept their position in a hierarchy. Women, however, after being treated as royalty for like 10 years, is hard for them to downsize. They are just bitter they lost that privilege.
