Actually, philosophers do seem to be interested in questions of existence. For example, Bertrand Russell probably mentioned that "I think, therefore I am" is wrong — what does "I" mean? Particularly if the mind is a collection of things, and the notion of "I" is a useful illusion, an oversimplification. Maybe an improvement is, "Something thinks, therefore it is." I think that there's various parts of philosophy, and not all topics will interest any given person, nor will the work of all philosophers. Maybe various institutions (like universities and priesthoods of professional philosophers) promote practices one doesn't like, like big software companies enforcing only Java-the-language. But I think the subject naturally attracts people who ask themselves why they're doing what they're doing, and other such questions.
