What better training ground that real life? Experienced pilots have the very same "quality" type rating as non experienced ones plus years of on the job training. You are either talking your own shop (ie you are inexperienced yourself or make money from these poor folk) or you do not know what you are talking about.
To the problem of experience and training we can add the problem of ability. The latest schemes only select on the ability to pay. So you end up with inexperienced and unable pilots whose only virtue is the ability to make someone else rich.
