i'm all for opening up state lines to encourage competition.
but i think they need to remove the antitrust exemption first, otherwise the private companies will continue to agree on a certain price and this negates real competition.
a bill was introduced Set. 17th and according to this page
House Panel OKs Bill Stripping Health Insurance Antitrust Exemption this is close (or closer) to happening.
and i really think, as i said before, the private companies can take a smaller profit margin rather than simply going out of business altogether.
