It's all bluff on the part of those who want to leave the West. Most Western Somalis are too well adjusted to living in the West & none of them have will power to adjust to a newer society, such as Somalia etc.
Its not all a bluff many have left after saving a considerable amount and have invested in businesses.
Hedonistic people will want to resume in the west as they subconsciously believe its comforts will always be there regardless.
This is a false perception of reality as we can see how the dynamics can shift easy look at the economy, tensions between races, increasing poverty statistics.
Its not what it use to be anymore and is on the verge of collapse.
