You should be angry at the International Manufacturing Association, not Clinton. They are the ones supporting Hyatt, not Clinton. Place blame where blame is due, not elsewhere.
I'm not sure I agree with this, but I'm speaking form personal experience. While I'll agree I probably spent at least 1080 hours in direct contact with students, I would not call that only 20% of my time as a teacher. I probably spent almost as much time planning, grading, tutoring, researching, etc. We'll call that time about 1,000 hours. That's 1080+1000 = 2080, approximately the same amount of time as any normal full time job in America.
