Medical cost seems to be a vicious circle.
For the most part, not optional but necessary.
Most of the profession is relatively high price. Not just the Doctor, but the specialists and the offices and equipment... Overall a high overhead.
Medical lawsuits are expensive, thus high insurance costs.
This leads to abundance of caution. No prescriptions or treatment without extensive, all inclusive tests of all kinds, as well as (usually) full blood tests.
Add to that the influence of the pharmaceutical companies (perks) and the "good health" bonuses from associated health plans, and we're left with a "take it or leave it option", as a patient.
Perhaps, some time in the future, a more level playing field, but I fear, not in my lifetime. Even the so called advances, such as "talk to the doctor" calling, come with a high price tag.
