We have a similar levy in the USA, except it's mostly paid by people that can pay for healthcare, so an aspirin costs $100 when administered by a hospital.
And since insurance companies are smart, they negotiate down those exorbitant rates to something more reasonable, so much of the burden lies on those stuck in the middle -- they don't have enough income to pay for health insurance, but have enough assets to pay for healthcare so they end up paying the exhorbitant rates because most people don't have time to rationally evaluate and price out their healthcare and choose the most cost effective provider, and even if they do have the time, the hospital can't tell you how much it's going to cost until the work is done and they bill you.
Even when you are insured and have a procedure done by a doctor that's covered by your healthcare plan, sometimes another provider (like an anesthesiologist) will do part of the procedure and you end up paying $10,000 or more out of pocket for his services.
Our system is broken in so many ways.
