Former teacher here. I regret getting an M.Ed. The only consolation is I made some good friends when in the trenches of student teaching. I am still not certified (despite four years of teaching experience) because the hoop-jumping to get certified was one more absurdity in an infuriating system designed to put up pointless roadblocks. The bottom line is teachers are given responsibility without authority, and made me want to throat-punch someone. The system holds teachers hostage to the human instinct to protect children. Anyone who can leave this profession, will--except those lucky enough to be working in a decent school or district.
