I live in NZ so my experience won't match I guess but;

1st year university (we don't have college) - 300 people in the lecture hall, good lecturers give informative, clear lectures that anticipate questions. Other lecturers do not have good enough English to do more than recite. If they are asked questions they repeat what they have said and often have to go back a page in their script if they are interrupted.

Unless you already have a well paid job and qualifications and skills the employer doesn't want to lose paying for training is pretty much up to the employee.
