Are they seriously comparing teachers to architects? Architects have to design functional, attractive buildings that are structurally sound. If they screw up, the results can be devastating.
Education classes are a breeze, and there are no real consequences if a teacher screws up, at least not any that the teacher has to face. If a kid doesn't learn, a bad teacher can easily blame it on every other factor, except her teaching, if she so wishes. Laying off teachers is difficult, and it is pretty much impossible to fire a teacher before the school year is over. They make a full salary for 9 months of work.
One of my best friends is a teacher, and I think she is a really good teacher. She does bungee roping barbie with her algebra students to show them real world applications of mathematic equations. She loves teaching statistics, so she is going to start a new AP statistics program at her high school next year. She is really dedicated, and it sounds like her kids are really learning.
Good teachers are absolutely worth their salaries, the problem is when the mediocre teachers pretend to be as valuable as the good teachers.
