It is worth acknowledging that education tends to be an easy major at US universities because the public supporting public universities has an incentive to firehose students into a steady supply of new teachers. It's a wide funnel optimized against false negatives because the profession has a high attrition rate among recent hires.

I was talking with a freshly minted math teacher yesterday at the soccer field. He was as enthusiastic as one might imagine a 23 year old would be after a year spent with middle achieving suburban Atlanta kids in a 10th grade math class. His first response when I asked how he liked teaching, 'It's a job. It's not like my internship [in a university town] was.' He likes math; teenagers not so much.
