I agree with Liquid, the old man probably couldn't differentiate different African groups. Besides, yes Somalis lived and worked in the Gulf for centuries, we were poor nomads (still are) but we never traded that for a lifestyle of slavery. Being a paid servant/maid (jaariyad/booyaas) and being a slave held against will are two distinct things. A servant can quit their work tomorrow and go back to their family. A slave is beholden to his/her Master although many a times a servant becomes trapped into slavery and their economic migrant status is taken advantage of.
Interesting documentary btw. I've noticed a few things,
-Oil is what helped create Saudi Arabia and just as it was instrumental in its construction, it will destroy it one day.
-The tribes of central Arabia were lawless and warring like Somalis such as Reer Xaniifah, Reer Asad, Reer Kilaab etc but Aal Sacuud were smart in some ways. They married the daughters of all rival chiefs and showered them with crazy wealth to buy their allegiance. By contrast the Somali leadership only enrich their own and then we wonder why the rest of the country show opposition.
-King Sacuud of the 50s/60s missed out on a chance to produce a powerful Arab global superpower when he let General Eisenhower put friction between him and Nasser of Egypt. They could have achieved great things together i.e. take back the Suez Canal from European economic overlords, monopolize Oil for the Arabs and put an end to Israel's existence. Laakin wuxuu sharaf iyo cizzo ka dalbay gaalo, dad aan diin iyo amaano aqoon. The same gaalo who betrayed King Faisal and offered 2 billion (which must have been a hell of a lot of money in the 60s) to Isreal.
-I never appreciate 'Jihadis' who seek the help and assistance of Non Muslims to fight their wars. I mean, whose to say the Jihadis trained by the CIA to fight US' archenemy the Soviets weren't also pay-rolled to start some unrest in their home countries too.
-The seemingly good guys were always assasinated in that era. Prez Kennedy, King Faisal, Malik Shabaaz, MLK, Prez Sharmaarke etc.
-I hate when people refer to 'anti-Jews' as "Anti-Semitic" since i consider it a clear linguistic error. Semitic is a Biblical reference to all descendants of Sem the son of Noah. From the Aztecs of Rome to the Kings of Axum, all are somewhat descendants of Sem. The Jews have no sole claim or right to that name. They (Jews) are followers of Judah and should be referred to as such.
-There is every reason to suggest the incidents of 9/11 was birthed by talks between Bush and Abdullah. Bush convinces Abdullah this would strengthen Saudi as an "ally" in the upcoming War on Terror and would help retain the Saudis as the Masters of the Arab World.
I still remember a conversation i had with a Saudi student at my campus, whose extended cousins were related to the Royal Family, he told me many of the Saudi Royals were educated in private institutions, many of whom are young political elites that want to re-ignite the power of the Muslims but the handpicking of the King is done by the seniors who are in constant consultation with US Generals.

The seniors already know the US are simply interested in maintaining the stream of Oil but they feel they are so embroiled in this relationship that any other path (such as pulling out their billion dollar assets from the US stock markets and instead relying on their role as the Muslim patronages of the Haramain) would lead them to lose their status.
Reminds me of the story of Malik ibn Nuwayrah, he had the respect and allegiance of his people, but when he had ambitions that were Unislamic, he sought the alliance of a soothsayer who misled him, made him at war with his own tribesmen, destroyed his marriage and left him for dirt when the tide turned and Khalid bin Waleed seized his land. Today, the Saudi Royals are watching as one by one the Arab rulers around them are losing power sanctioned by US support and the Palestinians are still occupied. When you don't come correct at the height of your power, you have nothing to fall back on when you are weak.
