Sad thing is I think there is a possibility Obamacare may have had a hand in raising drug costs, even if indirectly. I could easily see pharmaceutical companies, being for profit businesses selling a product, having some round table meeting and being all like "Ok so now that it's law, why not just hawk the price up for all our life sustaining pills. Medicare can't negotiate or haggle, we'll make tons more profit and if anyone complains we'll just chalk it up to Obamacare made me do it."
It's kind of like a certain telecom moving out of the West claiming it's the result of the FCC's Net Neutrality ruling. When in fact, it had nothing to do with it. The nature of business is often deception and misdirection.
