The criticism's been made that Joe Quesada got rid of Spider-Man's marriage, just due to his personal preference on the matter. There's sometimes the assumption that the next Editor in Chief of Marvel can bring back the marriage for the same reason.
Agree or disagree with him, Quesada did articulate his motivations for preferring Spider-Man to be single. So presumably any future EIC will have to articulate the benefits for reversing the decision, and make a case for it being a good idea
So what reasons could he or she give? How would the Spider-Man comics benefit by the restoration of the marriage? What does it provide the writers? How could it contribute to increased sales?
Note- Why Marvel's next EIC would want to keep Spider-Man a bachelor is a topic for another thread.
