Investor's Business Daily published some research on government-run healthcare. The Pacific Research Institute did a study on healthcare spending in order to compare the cost of private versus government healthcare. I'm sure that you know what is coming, but here are the details. Don't mention these statistics to a Democrat.
The results are clear: Since 1970 -- even without the prescription drug benefit -- Medicare's costs have risen 34% more, per patient, than the combined costs of all health care in America apart from Medicare and Medicaid, the vast majority of which is purchased through the private sector.
Since 1970, the per-patient costs of all health care apart from Medicare and Medicaid have risen from $364 to $7,119, while Medicare's per-patient costs have risen from $368 to $9,634. Medicare's costs have risen $2,511 more per patient.
Just remember that healthcare isn't really about your health or making it more affordable ... it is all about power.
