The difference is that those in ESL without any real interest in education, knowledge and self-growth are not eager to educate themselves and to develop. In competition with others for jobs and positions, they will pretend to know everything and will not accept to be questioned. That's to protect themselvs and to cover up their own incompetence. Typical for DOSes at crappy training centres, many if not all of them without any legitimate degree in a relevant major.The same for stupid Chinese High School principals who have bribed themselves into the position they now have.
