That's a very interesting "study" you've conducted. I don't think your theory is valid- in spite of the nutritional benefits of red meat, it doesn't parallel supplementing with simple Glutamine, Creatine, BCAAs, and whey. It's not like it's a budget killer to anyone to powders of all of the above.
I do agree with your point, supplements such as Gaspari's Superpump250 (which works phenomenally, i might add) are often used as a crutch. In spite of possible benefits of these, they are not nearly worth the 100+ bucks you usually have to shell out each month to stay consistent with them. Often these "super-supplements" become a crutch and a financial burden. I don't believe that you can apply this statement to all supplements in general, however.
