Here is a URL regarding the agenda to remove Christianity from society at large. In a nutshell, it discusses the role Horace Mann, the "Father of the common public school", and Robert Owen, one of the fathers of modern socialism, and others.

I've been in the schools. I taught 7-12 science for five years, two of those after I had already been burned out once and took a break to raise my children to school age. In Missouri, the average new teacher burns out and quits the public school system after 3 years, never to return. Sadly, with only five years of experience, I've got more teaching experience than >50% of the Missouri teaching population. Most of the burnout is due to the fact that the average teacher works 60+ hours a week during the school year, discipline is at an all time ineffective low, and the state's demand for continuing education for certification. It is difficult to find balance in your life as a teacher.

Life as a substitute is better because you have time to live your life outside, but in the classroom it can be worse because in the students' eyes, you're not a "real teacher". IME, the classes who behaved best for substitutes faced double the consequences for misbehavior upon the teacher's return.

Good Luck,
