Teachers used to teach their students Reading, 'Riting, and 'Rithmatic. Children learned when that was what school was all about.
Teachers are maligned by those who find doing so is profitable.
They have to implement programs that exist only to make money for the companies who design them and the salesmen who sell them to a school board who just cannot admit that they don't have all the answers and grab at whatever they think will make it look like they know what they are doing. Most of these programs have such a need to be justified, that rather than have time to actually teach children the teacher is expected to fill out forms and generate paperwork so the school district can have something to show as a way to appear to be doing what is best for children.
Teachers have been considered union thugs because, besides fighting for the proper education of children, they want to be treated like the professionals they are, not like they were the school marm on Little House on the Prairie.
And after all this it is now being suggested that teachers should be trained to act as armed guards and first responders in the event that someone may enter a school building with a gun.
School districts cannot afford basic classroom materials or the Professional Development programs teachers request, but they now seem to be able to afford guns and training so people can keep their assault weapons.
So on the one hand they are maligned as thugs, but then it is suggested they be armed.
It has now become standard procedure that when a social problem is recognized by the public, it is the teacher who is expected and required to be the one to handle it.
A novel idea might be to let the teachers teach without all those extra assignments.
