Considering education majors are as a group among the academically poorest performing majors, I think your concerns are unfounded. Consider also the educational fads like three-cueing that actively harmed children.

A few decades ago, most teachers did not have anything beyond high school education. While there are many valid defenses of public schooling, "public school teachers are more qualified" is not one of them, particularly given the miserable performance of many public schools - qualified teachers in 23 Baltimore schools failed to generate a single mathematically proficient student, and Baltimore is not alone. Credentials on their own don't mean anything if there's nothing worthwhile backing them. If anything, they are currently being used for gatekeeping purposes. For example, I have a Master's degree in CS and I was a TA, but if I were inclined to teach a CS at high schools, I have to spend a few thousand dollars and get a pointless certification.
