Yh, it probably is the refugee problem. A lot of somali males are starting to do well... I've noticed that children born of refugees, particularly males tend not to do as well as the women.
Ethiopians are a mixed bag. Some of them are affluent migrants, but a vast majority of them are migrants from the 1980's, from various famines, or political refugees from an oppressive government. We're sensitive to the Somali tahreb phenom as Somalis, but there are many Ethiopians and Eritreans crossing the Sinai, and making the death quest of getting into those boats we hear so much about. They are mostly from modest backgrounds in everything from literacy to class, and even in religion I believe they are a mixed bag with a 70/30 Christian to Muslim ratio. Even so, they're doing quite well for themselves in the US. Ethiopian women too! Somali women are doing well relative to Somali men. We could do so much better. There must be some cultural component. They aren't allergic to hardwork from what I've seen. Nigerians are another group that do well for themselves in the diaspora, men and women, but they're known for crime too. At least, they have a well-accomplished, exemplary side to their diasporan community to counter that.
Ethiopian guys are manlets with beak noses
As a woman, I'd say I'm a better judge of that. A number of them may be short, which I don't consider shorter guys in general undateable tbh, but they are attractive if you want to date men from the Horn, or from Africa in general. There are all kinds of attractive men in the world, so I'm not stuck on them, but they have some very attractive guys, no doubt about that.
