You don't need to be educated at all to be a class traitor, and I don't think you really need to be "deeply committed" so long as you're substantively mainly siding against your class interests, because that's what the word means. It's not a moral status of being absolved for the sin of being bourgeois and we shouldn't treat it as prohibitively restrictive for such a purpose. It's a simple descriptive term, and you can still be a "class traitor" to the bourgeoisie while being a piece of shit.
