I'm Dutch so I don't know to what extent my experience applies here and what it will do to your expectation on outcomes (teacher is a decently paid job with us, though definitely not high paying). The people I know in education are generally highly caring and work way more hours than their contract asks them to. When I was in school, I've definitely also had teachers that were not so good - in some cases that may have been because they were in a field where teaching was one of the few feasible careers (e.g. Latin/Greek) and it was not a fit for them, in other cases maybe there was also a lack of competition or accountability to an extent. Teaching is definitely viewed as a safe/fallback career option, but there are also lots of people who choose it specifically because they are passionate about it.
