Why not a single word from Dr. Krugman about the very questionable practices of, for example, Prescription Benefit Managers? PBMs receive large rebates (aka, "kick-backs") and, rather than passing along the savings to patients, they pocket hundreds of millions of dollars. President Trump and HHS Secretary Alex Azar made it very clear they will demand that these rebates be used to "lower the price at the pump" -- lower co-pays for patients when they get their drugs at the pharmacy.
When people say, "My drugs are too expensive," what they mean is "My co-pay" or "My deductible" is too expensive. Shame on Dr. Krugman for perpetuating the myth that drug prices are a one-dimensional issue. And shame on him for ignoring the many solid recommendations made by the President and his healthcare team. As the Yiddish proverb goes, "A half truth is a whole lie." It's the ecosystem, stupid.
