It's no doubt true and no doubt true in other arts too. I would say it's not necessary to look for patterns etc. but rather to understand that many people in all walks of life are not comfortable with who they are are what they are doing and why.

This alone leads to thinking they need more and more and all different kinds of things and 'other' methods to fill that hole of insecurity and inferiority.

Find your way, be happy. Love your way and you can then also love others ways. Thus there is nothing to feel inferior about.
