And as you have said, things may have changed and in two years, someone may have a very expensive qualification with no related employment with which to pay it back!
I cannot speak for the others but personally, I like these questions as it gives insight into the industry that I would dare say none of the general public know about. Good things (I'm based near home! Yay!!) and bad things (stupid rostering issues!!) are all realities in this business that people who are too busy choosing schools and finding the finances may not consider. I do understand that at some point, a decision has to be made and as with everything in life, nothing is certain, but still, it's nice to be broadening one's horizons while still on the ground.
