‘The Dangerous Gym Membership’?

Here’s a poor, unsuccessful letter I sent to the editor of the Washington Post:

The dangerous gym membership” [Jan. 12] claims that in Medicare Advantage, “advertising a plan as the go-to health insurance source for marathoners could lure in a healthier subscriber base, disrupting the rest of the market place in the process.” Oh?

Does it disrupt the market for sneakers when running shops advertise themselves to marathoners? Since when does giving consumers something they want disrupt the market? That’s why markets exist.

What’s disrupting the market for seniors’ health insurance is government—in this case, Congress’ counter-productive attempt to cross-subsidize the sick via price controls that forbid carriers to consider each applicant’s risk when offering and pricing health insurance.
