Since this thread is depressing as hell, mainly due to the morons spitting on the memory of a social worker because they can't bother themselves to read a one-page article, I'll share a nice story.
A friend of mine was married recently, and his wife is a social worker in Baltimore City. One of the speakers at their wedding was a young guy, around 20 years old, who has been on her case load for 5-6 years or so. He spoke about where his home life was when she entered the picture, and how she changed his entire perspective on life. He said he considers her to be like an older sister, somebody who cared for him and treated him like family when his life was very difficult. She also provided some guidance on how to pursue something more positive in his life, which led to him graduating high school and enrolling in college. He's now getting ready to graduate from college with a degree in something computer related.
That's what social workers do. They visit families, they provide resources, they offer counseling, and they help people. There are thousands and thousands of stories like that.
