Who are the real bullies?

I really appreciated this comment in the school-choice post on the Mises Blog.

The context is that “schools that don’t address bullying might lose federal funding from the Department of Education.”

“David C” replies,

Then by that standard, all the schools should lose funding, because I can tell you from experience that the big bullies in the schools are not students, but the teachers and administrators. The students are just copying their mentors. But this makes perfect sense, because the biggest bully of all are the state and federal governments who attack the taxpayer. The teachers and administrators are just taking marching orders from their bosses, who have driven out the passive workers long ago.
