I find it interesting that so many humans strive to improve their conditions.  Not all by any means.  Not even most.  But there are always those who look for a better way to peel a potato.  Some want to get rich.  Some just want to make things better.  This is one thing that sets all the races of humanity apart from the non-sapient species of the galaxy.  We are never content with the way things are, and we have the capacity to change the worlds.
