Could the rating organizations be biased to weigh disseminated coverage and care more than individual quality of care? Just a question, since I seem to get that impression these types of quality of life surveys.

As a USer with good insurance, it's a hard pill to swallow to trade next day doctor appointments, same day urgent care (not ER) with very short waits, and quick schedules for surgical procedures for the broader coverage other countries offer with more rationed care.
