Serving the Underserved

I am off to teach a course at Lee University titled, "Serving the Underserved". In preparing for this class, it has got me thinking (always a bad sign, usually it can be identified by a contorted look on my face and steam coming out of my ears), why, in the richest country of the world, are there still people who are "underserved"? Why, when I walk out of my office door, do I walk by people who are homeless, jobless, and without any support service? Why do we feel the need to look at the government to solve these problems? What happened to the second of the two most important commandments - "Thou shall love thy neighbor as you love yourself"? Even if you are not a Christian, at some level you must agree with that philosophy, right? What are your thoughts? How do we solve homelessness, drug addiction, domestic violence, child abuse, and all the other issues that plague our communities?
