I Don't Understand: Why?

I don't understand:

Why we can't have morality without dictating religion.
Why we can't have differences without hatred.
Why we can't have disagreements without belittlements.
Why we can't love a higher spirit, but each in our own way.
Why we can't feed the homeless but can rebuild the world.
Why we can't find charity for our neighbors but can pray for a stranger.
Why we can't see our own faults but can so easily find them in others.
Why we can't see the good but so readily point out the bad.

Why love doesn't return the gift of generosity.
Why we profess to value honesty then lie to protect ourselves.
Why success can't be won without deceit.
Why we abuse the world but cherish possessions.
Why profit means more than the method that achieves it.
Why what people say isn't what they mean.

Why we complain more about what we don't have instead of seeing what we've already been given.
Why we want so much when it's usually the simple things that make us happy.
Why we try to be someone and something we aren't instead of celebrating who we truly are.
Why we aren't more thankful for the people in our lives instead of the things in our lives...
