I dont really understand what pharmacists do other than organize medicine to hand out.
They actually underfo university level education to understand the biochemical mechanisms and actions of drugs,to better understand interactions with other drugs, or side effects on patients
Yes, but is that really necessary? Because their jobs generally just require them to fill prescriptions made by actual physicians.
Yes it is, since they are a member of patient's healthcare team, they can spot if there is an interaction that might be dangerous and get that change with your doctor's office.
I suppose that makes sense. They just seem like a bit of overkill in a medical industry that already costs way too much.
See in other countries they use pharmacist the same way, but do not have overpriced medical, ours actually don't add a lot of cost to medical care.
Fair enough. I've lived in other countries and with far better medical care (at least in terms of costs) so I am very resistant to US care. 
Yes considering health care facilities are largely  owned and operated by private business, profit unfortunately affects patient care and costs.
