The Supreme Court has it wrong. Technological advances will destroy private health insurance over the next decade.
Once genetic screening techniques are perfected, so that our propensity for each and every disease will be known from an early age, the only form of health insurance that makes sense will be the single payer form. The private health insurance industry will go the way of the dodo, as no responsible Canadian Government will allow an unregulated market in which Insurance Companies can cherry pick for coverage those with a low propensity to get sick while excluding those from coverage who are likely to do so.
We had better start now to develop a Health Care system that takes account of these evolving technologies. At least we have a better base to build on than our neighbours to the south.
