So, if I want to be a responsible teacher who cares about his students and who follows the line of "your success (as a student) is also my success (as a teacher)", I should make every effort I can to help them succeed. Rubbish training centres are not worthy of any such efforts

What a contradictory statement! It is not the TC that you make the effort for, it is the students that attend your classes.

[edited] I'm glad you don't teach young learners.
