Klein's email warned that such a plan would destroy the private insurance market. "[O]ur livelihood depends on health-system reform that achieves the right balance between what government can do and what private plans do best," he wrote.
As the paper notes, Klein made $2.73 million last year. So his livelihood probably isn't at stake here.
A spokeswoman told the paper: "On major issues of business-wide importance, we have given employees an opportunity to become involved -- and always voluntarily."
Hours after that story appeared, the company sent out a followup email telling employees how their family and friends could fill out their own postcards. An internal block prevented employees from forwarding the email, but TPMmuckraker obtained a screen-shot of it.
