even if the oil ran out some time in the future (which will happen eventually) Those countries created an extremely huge investments groups just like the abu dhabi group, kuwaiti foreign investment group, the kingdom investments (saudi)....
Those groups have literary invested in every industry in the world in almost every country out there, from China, Europe, India to the U.S.
The Income of some of these groups (like the Qatari and kuwaiti groups) have topped even their Oil Income, so unless the whole world fail some time in the future those countries wouldn't be wiped out (atleast financially).
Those Bedouins aren't as
dump as some thinks they are.
