  Medicare would not have 2% overhead if it served 30-year-olds.

Swing and a miss. Medicare does cover 30 year olds, you just have to be sick enough to qualify. So in fact Medicare covers the least profitable young folks.

Edit since responding to your prolific bad faith arguments got me throttled:

Your argument is that younger people would magically add to the overhead incurred by Medicare. My point is that Medicare's low overhead already includes younger people who are more likely to use expensive modes health care more frequently than the typical younger person. And even then Medicare denies claims at a much lower rate than for-profit insurance companies.

But somehow, adding more, healthier younger folks to Medicare would add to the overhead?

Nah.

Edit since I might as well address another bad faith argument:

  Medicare rate limits the number of new doctors allowed into the system
  every year, through the residency funding system.

Congress controls that funding. Medicare is the administrator. At best your phrasing is disingenuous.
