"Osama bin Laden had absolutely nothing whatsoever with Saudi Bin Laden Construction."
It substantiates nothing of the sort - it says it is a family business, there is no reason to believe he was not part of it
He had a degre in Civil engineering, yet there is no record of him ever having worked, so we can safely assume that he lived from the family billions which came from the family construction firm.
Nit-pick this as much as you like, but his money came from construction.
As usual, you are wrong.
