This is basically my view as well. I don't know if you'd call it objectification, but I tend to view people in the same way I view compilers; they're doing their best approximation at what they should, based what they're currently considering in light of how they've been taught to think. It's why I don't get outraged at people who treat other people as accessories; it's simply what they think will get them what they want (which, in my experience, is usually inflation of their ego, at least when this occurs at a local level).
So I suppose the ubiquity of objectification depends on what you define as objectification.
