This is an interesting question, and I've wondered if a Shakespearean audience might respond differently than a modern day audience to the possible message about arranged marriages in this play. From very early on in the play, readers are alerted to the fact that Lord Capulet is likely to arrange Juliet's marriage. Paris asks for Capulet's permission to marry Juliet, and Lord Capulet doesn't say "no." He asks Paris to wait and make an attempt to woo Juliet as well. Capulet might control her marriage, but he also wants Juliet to be happy. He wants her to be taken care of, but he wants a partner for her and not just a bread winner. As a parent, I can't fault Capulet's desire to control his daughter's future spouse, and I respect what he is looking for. Young teens might find it controlling, but that was normal back then.
I like playing the devil's advocate with my classes regarding this topic/question, but I'm also not defending something that the play doesn't seem to support. I think the play sends a very strong message about the importance of and appropriateness of arranged marriages. Paris is a well established, respected, cordial, and handsome man. He would be an excellent future husband for Juliet. She would likely learn to love him. That might sound coldhearted, but rushing to marry Romeo because of a belief in love at first sight ends in tragedy.
There is nothing beautiful about their deaths; it's a waste of human life. Had Juliet married Paris, she would likely have lived a long enough life to raise her own children with a husband that appears to be entirely devoted to her well being. I truly believe that Romeo would have "gotten over it" and fallen for some other girl the very next week. Look how quickly he gets over Rosaline. Capulet is making a marital decision based on logic. Juliet is making a marital decision based on emotion. When it comes to long term decisions, logic usually performs better.
