What is working? Big surprise: the free market and local adaptation. Now don't get me wrong, the best solution is still a long ways off: having consumers negotiate directly with healthcare providers. But this is more evidence in the failure of big, centralized, government planning.

What I would like to see:
1) conversion of ALL employer-provided plans to personal plans. Allow employers to deduct from their taxable income any pay to the employee which goes to cover their personal/family health insurance costs. This would allow for greater mobility of the worker to retain an insurance plan they like even if they change employers. Additionally, it would incentivize businesses to offer competitive benefits to employees without penalizing them.
2) A Federal law which prohibits limitations on the purchasing of health insurance across state lines.
3) Encourage insurers to split their coverage into two types: health maintenance and catastrophic coverage. Health maintenance coverage applies to routine doctor visits, well-baby checkups, immunizations, examinations, emergency room visits (for some things), etc. Catastrophic coverage would be for specific illnesses - especially those identified by genetic testing or family proclivity - such as cancer, ALS, etc.
