As a North African, your inability to respect the right to self determination of a an aggreived minority population has nothing to do with the "economic integration of North Africa".
The reality is we're all subjugated. Moroccans, Sahrawis, or Americans. And we're all minorities in Morocco: Sahrawis, Riffis, Chlouh, Doukkali, Chamá-lo, Fassi, Meknessi, Soussi, and I can keep going. The issues people are saying about the Moroccan government's behaviour in the Sahara are just as true in other places in Morocco. And they're just as bad as what any government who's taken by oligarchs does to its population.
"Economic integration" = more trade = more power together.
