One of the greatest curses on the USA is teachers unions.
We are doomed unless these union are broken, it is that simple.
One big problem (in my opinion) is that the students do not get an honest examination of labor unions from their teachers. I, personally, am aware of harassment, vandalism, sabotage, assault, battery, and all-around malfeasance perpetrated by members of labor unions. I know of not one single such instance perpetrated by an employer, NOT ONE. Get a public school teacher to point this out and I will mail you a premium cigar. Ain’t gonna happen.
