They somehow segue into other reasons for these contradictions. When you are not disposed to keep learning, then what your original foundation was remains despite the ever changing world in which we live in. Keeping things simple makes it easy for those who will not face ambiguity with honesty.

We are not all cookie cutouts of someone else's imagination. We are real and have hopes and dreams like the rest of humanity. So for us to be labeled as insignificant or worthless due to life slapping down hard on our heads is disingenuous and ignorant. Unfortunately our nation is full of these types who can only see winning at every turn as the answer to how life should be structured. They are the survival of the fittest crowd who will not allow themselves to learn a new way of seeing our existence. They cannot crawl up out of the cave that has them trapped to see that we can do anything, not just what we are told to do.
