There is a report that the cost of health care will rise to 20% of the federal budget with a total cost of $4 trillion annually by 2017 (here).
This is way beyond what this country can afford. Well at least it's more than we can afford if we want to avoid spending our children and grandchildren into a debt that only be paid off by massive rampant inflation.
So which candidate will admit this? None. Taking this on is political suicide. Remember when Walter Mondale admitted that he would raise taxes? What happened? He won exactly one state (and the District of Columbia) - by the way, that was exactly why I voted for him. Admit today that you intend to do the things that must be done to really control these health care costs, and you might as well dig a deep hole and climb into it.
I've said before, and I'll say again, fiscal sanity is my one and only issue. I hope that someone gets it.
