Facebook and Google have entire training programs around the fact that a person is, indeed, worth 80k or more even without hitting the ground running. My understanding is that FB has a bootcamp of something on the order of 6 weeks for new engineering hires, with pair programming and all.
That's one of the perks of a big company over a startup for a young graduate - the company can afford the investment in their own potential talent, and can afford to take a loss on the few people who they were wrong about being worth the training.
