Health care plan treats citizens unequally

How is this fair? In one case, we have our DOJ refusing to follow through with the guilty Black Panthers in the voter intimidation case. Why are union members given all kinds of perks that ordinary citizens are not? Why are American citizens FORCED to buy government health care (since it's obvious that insurance companies will go out of business and, in other cases, any change in a health care policy will require going on the government plan) and others exempted from counting a "cadillac" policy as income? This is outrageous. How is this even legal, that the government can target certain individuals and excuse others for having the same benefit? Daily Caller:

A second way Obama’s health-care law helps unions is in the so-called “Cadillac” tax that applies to more expensive health-care plans.

For most of America, that tax begins when an employee’s health-care plan costs at least $10,200. After that, the plan will be taxed at 40 percent. For union-negotiated plans, the tax starts at $27,500 instead. Some estimates say this will save union members $60 billion over 10 years.
