I am sure they have demands and can invest accordingly, if they don't its entirely up to them, there is no reason to be jealous. I want resource sharing to be at the district level, looking at Shilaabo in Ethiopia, FGE takes biggest cut, gives crumbs to DDS, who then gives a tiny portion to Qoraxeey zone, and Shilaabo gets nothing but mag payments when people die drinking contaminated water due to extraction.50% for district alone will give half revenue to Kismayo, Badhaade & Jamaam districts by far the largest being Ksimayo. What are going to build there another Burj Khalifa?
That's not an equitable share. 10 & 20% are more than enough for district, the state will get 30% so it can balances with other districts within it's jurisdiction that has no sea access and the rest goes to FGS & FMS. You're talking about 200k people per district awarding them 50% is too disproportional. At the end of the day Jubaland is part of Somalia.
Now imagine if Shilaabo got the lion share, Qoraxey got the next biggest share, ,and Jigjiga and FGE got the smallest share, I am sure people of Shilaabo would not be dependent on FGE development request as their local budget would skyrocket and they can build and invest in their woreda or elsewhere through private investments. This is how things should be done in a decentralized federal system.
Obviously we could add a clause investments must be inside the country, as a form of regulating their use of the capital. Anything more would defeat the purpose of decentralization and we might as well stick to big brother central government from Mogadishu.
