What makes you think that? Hint: "it would make me feel bad if it were so" is not an acceptable answer. I'd like you to be specific and substantive. The measure for healthcare inflation is the consumer price index for medical care (CPIMEDSL). You can find it here:
https://fred.stlouisfed.org/series/CPIMEDSL
As you can see, the index stood at 385.712 in March 2010, when Obamacare passed into law. As you can also see, it stood at 487.664 in November 2018, which was the most recent month on record. So, that's a rise of 26.43%.
Before Obamacare passed, there'd been exactly 655 periods on record of that length. Of those 655, how many had 26.43% healthcare inflation or less?
The answer: Zero. Before Obamacare passed, the lowest healthcare inflation on record for a period of this length was 29.95%, in the period leading up to February of 1966. The highest was 137.10%, ending in the early 1980s.
So, if, as you can confirm with my link, we have no record of healthcare inflation ever being as low for as long as it's been since Obamacare passed, in what sense is what I said untrue? Be specific, please.
Look, I know what you're thinking. You're thinking "I wasn't aware there would be math on this test." Don't worry, the math is easy. I'm not even asking that you annualized rates. Just calculate the percentage. It's easy as can be. Take the second number, subtract the first, divided by the first, and multiply by 100. Simple.
Now, I know what you're thinking next. You're thinking, "I don't want to do the math, because I know it'll prove she's right and I'm an asshole for having pretended what she said wasn't true -- maybe I can change the subject or sidetrack her with a personal insult and get away with the last few scraps of my dignity." Please, resist the urge. Don't cower from the challenge. Take a look at the data and answer with honor: does it support my claim or not?
