“Last month, an Associated Press-Ipsos poll found that nearly 70 percent of Americans said they believed that people are ruder now than they were 20 or 30 years ago, and that children are among the worst offenders. (As annoyances, they tied with obnoxious cellphone users.)

…In 2002, only 9 percent of adults were able to say that the children they saw in public were ‘respectful toward adults,’ according to surveys done then by Public Agenda, a nonpartisan and nonprofit public opinion research group. In 2004, more than one in three teachers told Public Agenda pollsters they had seriously considered leaving their profession or knew a colleague who had left because of ‘intolerable’ student behavior.” (New York Times )
