We're as clever as we think we are but we'll be a lot cleverer when we learn to use not just one brain but to pool huge numbers of brains. We're at a level technologically where we can share information and think collectively about our problems. We do it in science all the time - there's no reason why we can't do it in other endeavors.
The reason we have poverty is that we have no imagination. There are a great many people accumulating what they think is vast wealth but it's only money... they don't know how to enjoy it because they have no imagination.
