Media outlets lately have emphasized the challenge of enticing healthy young adults to sign up for ObamaCare, "exactly the type of person insurance plans, states and the federal government are counting on to make health reform work," as the L.A. Times put it. These pieces are useful as far as they go, but miss a key point that Supreme Court Justice Samuel Alito managed to convey in many fewer words during last year's Supreme Court argument on ObamaCare.

Mr. Alito pointed out that young, healthy adults today spend an average of $854 a year on health care. ObamaCare would require them to buy insurance policies expected to cost roughly $5,800. The law, then, isn't just asking them to pay for "the services that they are going to consume," he continued. "The mandate is forcing these people to provide a huge subsidy to the insurance companies . . . to subsidize services that will be received by somebody else."

Since he puts it that way, why would they sign up for ObamaCare, especially since the alleged penalties will be negligible and likely unenforced?

Journalism celebrates the "five Ws" but a secret of our profession is that many of us disdain the fifth W—"why"—as if accurate analysis is somehow woolly and inferior to accurate transcription of simple facts like "who," "what," "when" and "where."

Here's another example. For 30 years, journalists have been "investigating" hospital pricing, which is neither competitive nor closely related to cost, invariably throwing up their hands and saying government must fix matters. Yet any reasoned analysis shows that government policy is why we have such a byzantine payment system in the first place, in which an ever-inflating health-care bill is allocated among "payer" groups via opaque political bargaining.
