I was responding circuitously to giving differential access to women based on longevity and emphasizing the reach that such notions would have.
Yes, the Obamacare pre-existing condition rules seem to largely state what the plan is going forward in the US on all of this.
This only flows one way over the long haul and that is towards universal coverage. As the number of "special interests" (e.g. pre-existing, or being a woman, short term-unemployed, student, employer-medicare doughnut hole, etc) stacks up, the argument for collective handling of health care will eventually win the day.
