Unfortunately you've said it in many words, when it should have been said it ONE. Good ground ops with constant and understood CRM with the operating flight crew is AN ESSENTIAL application to all operations. It is way past time that ground ops be appreciated for what they are, not just an ancillary to flight ops, but a portion of said ops.
Lets get back to the team application, air carriers must pay for the expertise they expect. GH companies must pay the staff for that expertise. Flt Crew get on a tug, tuggies get on the flt deck, brakemen to be (as they were) licenced engineers or crew members.
