This president has taken a $5. 6 trillion surplus and turned it into deficits as far as the eye can see. Health-care costs for the average American have gone up 64 percent; tuitions have gone up 35 percent; gasoline prices up 30 percent; Medicare premiums went up 17 percent a few days ago; prescription drugs are up 12 percent a year.
The cost for medicare premiums have risen, proportionally, more than the cost of prescription drugs. 
Medicare premiums have gone up by 17% but drug costs have only risen by 12%. It was likely difficult to determine because it needed to compare the two statements.
