I don't think it's hidden at all. He says in the Drugs section...

"The problem is that our drugs, on the whole, cost about 50% more. For name brand pharmaceuticals, we pay about 77% more. Why? Some will say that it’s because we’re wealthier and need to subsidize for the rest of the world. But even if we paid more based on our relative wealth, it would come to about a 30% premium, not the 77% we do pay."

So the problem is obvious. The issue is how to fix it. We in the U.S. can either enforce our own price controls which will break the system or we can force U.S. companies to charge more to other countries and take the chance of denying medicine to sick people because foreign governments won't accept the higher prices.

Not an attractive choice no matter how you slice it.
