I think we have some sort global identity crisis because of that. Religions are not sufficient enough and science doesn't even try to answer the question of "why?" but rather "how?". In result of that, we ended up with no ideology and no tools to build one for ourselves.
This is laughably ironic, because we really want some change in the way we live and think and yet, we don't turn back and evaluate what people came out with in the history.
