I have had several students who were scared stiff of stalls after poor initial instruction, and it was my task to fix that at a professional airline training school.
Given the reluctance to teach stalling properly, and the ubiquity of low-time instructors hours-building towards their ATPLs, it is very much a case of the blind leading the blind. It is,however, extremely difficult now to earn a decent living as an experienced flight instructor, so I don't see the situation changing anytime soon.
