While we in the US complain about taxi monopolies and root for services like Uber and Lyft, some folks in Khartoum Sudan are struggling with a similar, but more existential, local monopoly: the wheelbarrow syndicate!
Supported by the local government, there appears to be a private sector monopoly on wheelbarrows in Khartoum, at least according to the BBC. Local porters are banned from owning their own wheelbarrows and face a monopoly in the rental market.
The video link above implies that the local government is doing this to help offset the revenue loss that came from the independence of South Sudan and its oil. People those wheelbarrow monopoly enforcement fees must be REALLY HIGH.
