"If these operators are so bad, why is it no problem for them to acquire all the drivers they want?"
Prospector,
Is that a serious question? Why do you think they can get all the drivers they want? Have you ever been jumping up as hard as you can to grab hold of the bottom rung of the aviation ladder? Some people get onto the ladder easier than others, and most of us are lucky enough to work for decent operators, or at least learn fast enough to stay ahead of the curve long enough to get out and get a better job with a better operator.
Some don't. And there will always be the desperate but unlucky types who aren't as fortunate with that first job. Generally, I guess, these are the ones who we all read about in the papers and condemn. Well, as wrong as it is, this is the way things are, and the only way it will stop is for the relevant authorities to clamp down on the operators in question. The pilots they employ are just trying to make a start, and usually don't know any better.
We all know the result, it is the cause that needs to be eliminated.
Just my humble opinion...
NP.
