The rationale for your proposed tax on high-cost health insurance plans is that it would encourage people to purchase less-comprehensive coverage and thereby reduce health care spending.

If that’s a good idea, then why is it bad when insurers raise premiums?

Obviously, it’s because consistency is the hobgoblin of little minds. You small minded libertarian twerp. Duh: it’s good when the government raises prices and it’s bad when the market does. Any more questions?
