How do I convince my wife that our daughters 7000 text a month is harmful?

My wife and I disagree that too much texting can be harmful. My wife actually gets mad at me when I suggest limiting the number of texts our daughter can do a month. She's sees nothing wrong with the constant texting of our 16 year old daughter. She says at least she being social. I disagree and am tired of sounding like the bad guy and getting the quite treatment from my wife and daughter when I suggest a limit. Any suggestions?
