Why is it a "scare tactic" to point out reasons why millions of folks covered by good employer-sponsored group health plans like them, including the access they provide to the best doctors and specialists? National health care cannot be created out of a vacuum; the current system works well for a lot of people, and sticking millions of working folks on Medicare - especially folks represented by unions, who have fought hard for quality health care plans - is going to have to be explained and justified.
I think you're right that most employers could do without the hassle of running health care plans for their employees, which is why I noted in an earlier post that getting the employer community on board for national health care would be a wise thing politically to do. But as Austinfan points out, employers get to deduct the cost of health care just as they do the cost of current wages, a situation that allows companies to compete with each other on the basis of quality health plans. As much as employers would, all other things being equal, seek to avoid administering health care plans, they recognize that a fundamental tool for retaining the best talent is to offer more than just wages. There's a reason IBC advertises as much as it does - it seeks to present itself as a quality brand to employees so they demand their employers offer IBC plans with IBC networks..
