Byron,
I think your spectacles are too rose tinted - you don't have to be an apologist for the Dos Santos regime, to be an informed LOM shareholder, just realistic.
He has been in power now for 32 years and started as a MPLA marxist with Soviet support in the Cold war that ripped the country apart. To survive that long in changing circumstances suggests a considerable degree of political acumen despite having the luck of his gifted UNITA adversary Savimbi taking several bullets in 2002. Nonetheless became a classical crony capitalist and his daughter is one of the wealthiest women in Angola. He controls Angola in the model of a caesaristic dictatorship. The personality cult is better explained in this link:

The Angolan government get plenty of money from oil exports (or the associated private companies do) but little of it goes on needed infrastructure... yet there are lots of expensive European 4 wheel drives cruising around Luanda.

I would suggest the better comparisons regarding corruption would be with Namibia or Botswana ( you can include Queensland if you must insist), Angola does not compare that well. I agree LOM have no money for bribes!

Well for the future there may be some sort of "arranged marriage" with Portugal that might benefit both hapless countries.

There was an assassination attempt on him in 2010 and younger Angolans have a poor regard for him and the ruling class. He is at risk politically unless there is significant change as per Tunisia, Egypt, Libya (and Syria at the moment). The "Arab spring" may spread south and he and his colleagues will know this.
