It strikes me that the main potential actual value of this kind of whining is a kind of in-group bias. As in the fact that having a common "enemy" can produce a strong bond.
But on the flipside, externalizing all blame makes it hard to solve any kind of problem.
I think the solution is to see the in-group as a team that is working to overcome the out-group. So the locus of control is internal, but there's still a common foe.
