Make it 99%. Needless and useless. Body was made to heal itself unless you abuse it.

When you pay nothing, you get nothing. Free open-ended no user-fee encourages waste. People go to doctors for the slightest discomfort, and doctors feel obliged to treat it with drugs. If they do not  prescribe a medication or procedure they are viewed as ignorant. Canadian doctors have become unwitting drug pushers to the delight of drug industry.

Using needless medication (or even vitamins) simply weakens, nay destroys, body's natural immune system. Drugs and doctors do more harm than good.

Canadian doctors are second rate anyway, since the best of the local graduates seek the more lucrative US market if they can, leaving the riff-raff behind. We do get top notch international doctors, but they are driving cabs. The running joke in GTA is that for competent, speedy, and cheap medical advice, hail a cab.
