Employer-paid medical insurance only exists today because: (1) the government allows private-sector employers to deduct the cost of this insurance, and (2) the government treats this benefit differently than almost any other one by allowing employees to be insured without reporting it as a taxable benefit on their tax returns.
So in effect, the government heavily subsidizes your medical care ... which means that it's hard to get all worked up when that same government imposes a tax on it. There are a lot of things wrong with the ACA, but this "Cadillac Tax" is far from the worst part of it.
I'd say your premises are faulty.
