You need to know Arabic in order to watch but basically he says that it got hard for his family to stay there in UAE after they grew up and there was no future, so decided to go to Europe for better future prospects.
Most of his viewers are Arabs but I really feel sorry for the Somalis with Somali citizenship who were born and lived their whole life in UAE but struggle to afford living there with the rising living expenses. You need to be wealthy to live there comfortably and in a country with very strict immigration laws and little financial security, some of them have no other option but to move back to Somalia or move elsewhere. Some of them try tahriibing to Europe while I have heard Turkey is a popular destination worth trying to move to, but some just decide to go back. Be aware that the dilemma of growing up in UAE with little to no future prospects is just not present in the Somali community, but is present in other foreign communities as well.
