Three kinds of people

I believe that the US is made up of three kinds of people:

• Those that are always looking at everything with a "What's in it for me?" attitude.
• Those who are willing to be led like sheep without critical thought, i.e., the majority of Democrats and Republicans.
• Everybody else

Trouble is the majority of our country fits into the first two categories. I have never felt that we have a truly united nation, at least not during my lifetime. As long as our country remains embedded in the first two categories, we never will.
