My intention was to highlight that “good teachers are scarce resources.” I didn’t mean to suggest a causal link between a country’s development stage and the quantity of its good teachers. My observation was simply that developed countries tend to have more educational institutions. While more institutions might not automatically equate to better ones, a larger pool of teachers could increase the probability of finding more good teachers.
