The article makes the argument that much of Saudi's aid goes to causes that do not benefit the general public (and, in fact, do quite the opposite in the long run). In terms of employment provided to Pakistanis, the dark side of that, as always in these cases, is brain drain - since it is not just construction workers that come over to work in the Gulf.

Of course there is the oil, and everyone in the world is willing to do cartwheels for that. So that's definitely hard to argue with. But not every country that purchases oil at a cheaper price from the Saudis is so actively importing the Gulf worldview to their own land (i.e. Bangladesh being one that immediately comes to mind).
