You know, one of the big problems we have in the USA is a lack of unity.  The height of our assemblage was World War II.  99% of Americans were united to defeat the totalitarians in Germany, Italy, and Japan.  But now, it's a 60-40 split: 60% traditional Americans and 40 don't like the country very much.  Forty percent are on the side that basically thinks everything needs to change.  

There's another big reason why this division is taking place, and that is delusion.  Many of us in America live in a delusional bubble, not in the real world.  We don't want the real world.  We don't want to go anywhere near the real world.  We don't want to deal with reality.
