I think academia is one of those special places where a lot of people who enter it are altruistic and idealistic, and consider it a part of their identity to make a change in the world in a larger sense. You are literally taking a pay-cut, willingly, in order to make the world a better place. At least in theory. So, in that sense, academia is (or at least used to be) more akin to monasteries than corporations.
Not that other jobs aren't making a change in the world, but you know what I mean. It's one thing to be a knowingly replaceable cog in a team that tries to offer more effective ads, and it's quite another to singularly, completely in isolation, try to devote your life trying to invent the MRI, where if you fail the MRI may never come to exist. So yes, a lot of people in academia traditionally do ascribe a big part of their identity to their jobs, but I think this goes beyond the superficial sense you describe (i.e. I'm so boring and soulless that my work defines me).
Which is also why it's such a big deal when some academics are found to be 'cheating' the system (again, see monasteries). Traditionally, the whole edifice has been based on 'honor', but the tide seems to be changing; the rampant corporatisation of academia has been a very recent phenomenon, and now that the inevitable shills and snake-oil merchants have entered the game, we don't quite know how to handle them.

This is a pretty interesting take. I feel that it may be even a bit "western " if not 'American ' centric.
In my country Academia is perceived as a "ladder" in the socioeconomic level. It's one of few ways people coming from low class can actually climb their SE level. As such, there is a different kind of pressure one side, and on the other, a lot of people are 'living their best life' doing the academia dance.
