Depends on a lot things. Most of the hard working Somali guys I know were born in the diaspora. Don't get me wrong, I know a couple hardworking Somalis that were born and raised in Somalia and moved west. But I noticed there's a noticeable difference between the two. Although I could be wrong about this, but this is what I noticed around me.
I can see Somali migrants getting the taste of the "good life" and being content with where they stand because they know its miles better than what they had to offer back home.
