Some large companies like McDonald's threatened to drop health insurance entirely or double rates in order to avoid the modest increase in life time coverage limits to take effect this year. The cap will increase each year until 2014 when it is eliminated. To avoid an embarrassment right before the election the Obama Administration has granted them a one year wavier.
The waiver affects about a million workers, the rest probably already have limits that are higher than this year's standard. These companies have said they will request a waiver every year through 2014 when the limit is completely lifted. After that it won't do them any good to make threats as there will regulations to provide affordable coverage including requirements that most of the premium must actually be spent on healthcare.
The insurance companies will still be allowed gouge huge profits but it's a start.
