Post-genomic era = socialized medicine?

Over at my other weblog there is a post up, Genomics and socialized health care, which asks if the new DNA era might not explode the acturial edifice that is modern health insurance in the United States. I suspect in this case many will welcome a "broken" system which needs to be replaced by a universal single-payer system, at least on the basal level. But, with privilege comes responsibilities. I suspect that the overturning the old system of health insurance, which was predicated on imperfect knowledge, will be correlated with the rise of a new system where particular values common within the society will shape the extent and relevance of genetic "screening."
