One of the biggest changes is the public's loss of respect and support for public education. There has been a concerted effort over the past 30+ years by the right to portray public education (government schools as one idiot always made it a point to call them) in the worst possible light. As a result, respect for teachers and the educational process is at an all time low. The days of most parents siding with the school or believing the teacher are over. Today, the first response for many is to defend the kid and immediately accuse the school/teacher of some type of wrongdoing. Students know this and play it to the hilt. The degree to which students are able to manipulate their parents is astonishing.
