The countries ahead of us are all relatively small and more or less homogenous.
You've got it. The USA has a societal strata from the world's bottom to the world's top. You gotcher illegal aliens living 30 to a small house, crack dealers filling the projects, and then you gotcher billionnaires whose feet never touch the ground. And still (yet) some middle class stuffed in between!
We are sorely lacking in the proper way to educate our children, however. Gay months and global warming are wasting our kiddies' time when other countries still have the 3R curriculum.
