The second sentence is "We tend to blame the high prices on things like drugs and medical equipment, in part because the price tag for many life-saving drugs is less than half the U.S. price in Canada or Europe."
Its point is that drug prices are only part of the issue.
Quoting https://www.cdc.gov/nchs/fastats/health-expenditures.htm for "Percent of national health expenditures":
* for hospital care: 32.3% (2015)
* for nursing care facilities and continuing care retirement communities: 4.9% (2015)
* for physician and clinical services: 19.8% (2015)
* for prescription drugs: 10.1% (2015)
If drugs were free, expenditures would go down only 10%.
If "health expenditures for physician and clinical services" were cut in half, it would also go down 10%.
In any case, neither alone are enough to explain why we pay "more than twice as much per person for health care as other wealthy countries".
