Pretty much the House of Saud strategy, and may be the strategy of every powerful family there is out there.
In the House of Saud case, its basically 'brother-stab-brother' process to become a king, the children nodes(cousins) in the tree generally get contracts to build airports, roads, or become police commissioner of some city. More powerful cousins get to become foreign ministers and run the economy etc.
Cousins who fork off too far away from the branch, typically settle for pensions and may be get their kid's educations in some foreign university sponsored. But again these sort of cousins eventually are the last generation to receive these draws. Because if you let power slip, its basically over. In things like these, money follows power.
Recently I heard of a similar case here in India. Where family politics had forked off a colleague too far away from the home branch. Or he would be pretty darn rich. Apparently his great grandad was a major feudal lord, his father settled for draws, the more powerful uncles have now pushed most other cousins out. And they and children pretty much keep every thing for themselves.
Once you get to a non-trivial money to give away in inheritance, bringing order to family politics is another big thing to do.
Political families in the Sub continent are another interesting thing. Every decade you see a powerful brother/cousin die. Only one survives. Then the game starts again between his kids :)
