Conrail might be a better alternative model. It really did succeed well enough to re-float and become a competitive endeavour.

The state probably did a better job than a private takeover could have because: - They had effectively infinite backstop-- they could afford to spend years and front load a lot of costs to fix the mess - They had a mandate to restructure the sector beyond a single company. I'd expect a nationalized Intel would have an easier time pivoting to new models, while private investors might be too afraid of killing their current golden geese for, say, a full fab spin-off or becoming a more aggressive x86 licensor.
