These are some books and links that have been helping me to dream church. Please let me know if you have any suggestions! I'm especially interested in video references!
Andy Stanley pastors a set of churches in the Atlanta Area. His book, Deep & Wide: Creating Churches Unchurched People Love to Attend, is great.
The book, White Trash: The 400 Year Untold History of Race In America, by Nancy Isenberg was really important for my learning about class in America. LINK
This series of videos is an excellent resource for discussions about class.
