I don't see why. People are stupid and careless. There's no reason to think that being employed in a nationalised industry would mean only the clever people would stay. In fact that there are many reasons to think that upon nationalisation the clever people would all leave. Thus nationalisation would increase the likelihood of such bone-headed moves.
That's the way it usually seems to go. Accountability seems to be something that the private sector does more enthusiastically than the public sector.
