@bud heishman Equipment and the rest is important, but a lot of skiers are thinking that it is the equipment and are spending needless money instead of money on instruction to fix the problem. Good instructors like yourself will identify technique and when required suggest equipment setup changes if required. A lot of skiers don't go through those steps unfortunately.
The instructors job is to accurately diagnose the CAUSE of skiing performance issues and address the real cause and if he/she can not remedy the issue, refer their client to a specialist who can. This is very similar to visiting your general practitioner for an ailment. His job is to diagnose the cause of your symptoms. If the cause is something within his area of expertise he will prescribe a solution, but if it is outside his expertise he will refer you to a specialist.
Sometimes the causes are technique? Many times they lie in one of the other three areas of equipment, physiology, psychology. In my opinion a good instructor should be able to identify the real cause of performance problems, not just the symptoms and should be able to reconcile any technique or psychological issues within the scope of on hill lessons and, at the least, be able to identify and differentiate between alignment issues and technique issues and refer equipment and alignment issues to a specialist whom they know and trust to fix the problem.
