I'm not sure it's possible to convey how absolutely deadlocked any legal changes have become in the US. Jon Stewart fought for years to get September 11th first-responders the healthcare they were promised, it was a single page of extremely popular bi-partisan legislation.
The system is as it is because that's the way it was in the 90s or so, and since there's no pressing need and no one has a reason to fight for years to change this particular aspect it will continue this way. Possibly for the next millennia or so.
