What Problem is Network Neutrality Solving?

Not everybody has been convinced that "network neutrality" rules are a terribly good way to solve the problem of unfair business competition. 

As a practical matter, U.S. "network neutrality" rules mean that Internet service providers can sell consumers one type of Internet access service, namely a "best effort" class of service that does not prioritize any packets, at any time, for any reason save security. 

For a person who wants to watch video or use VoIP at times of network congestion, that is not terribly helpful.
