Yes but you extrapolated what you learned "in a lab" to what kinds of things you could learn and the value to your education, and concluded that it should be left to PhDs. I would suggest that if you did clinical research in a Hospital, you would have come to the opposite conclusion. You chose something far afield from what you plan to do. But you could have actually done research in the field you plan to work in. If you wanted to do specialty X, you could have done a study in X, doing procedures, testing meds, or doing imaging of patients in field X. That's the kind of research you'd generally do in the course of medical training, not bench stuff. That in fact would impact your learning and skill-set and knowledge base in the field you were going into. You either get to read about studies in field X and tell your patients about them, or you get to be the guy who actually did that research. That's hugely different. and you would never have concluded that that kind of research should be left to PhDs. I think you are trying to extrapolate a premed lab experience to research generally, and it doesn't work here.
