We literally spend most of our lives fighting over fancy pieces of paper we're deluded into valuing more than one another, talk about a waste of time.
The unexamined life is not worth living. In the US at least, we are discouraged from asking the questions that can provide us some semblance of meaning based on what we actually value during our brief existence, because considering the big questions about the nature of being distract us from collecting more fancy pieces of paper for the master's next penis shaped space rocket.
IMHO, the ability to ask and really feel the importance of why is precisely what makes our existence more meaningful than an ant's. Rejecting philosophical inquiry and living a life of mindless acquisition and gluttony makes one about as sapient as said ant. You're just following someone else's script, and that someone usually has an agenda of maximizing your productivity and consumption with that script, so your life is more their life to spend than yours to experience at that point.
