The problem lies in the information gap that exists between rural communities and wealthy communities. The wealthy communities have people that have gone to top colleges providing information and knowledge to young kids, and rural communities don't, plain and simple.
Technology has the opportunity to change this, and although it hasn't drastically altered the information gap yet as it relates to college counseling, it is starting to. ConnectEDU is the most interesting technology company working on this problem that I'm aware of right now, but I'd love to hear about others as well.
