Health insurance companies have had their profits capped at a percentage of revenues. That means that to grow profits, they must increase revenue. Which means incentives to increase care and increase costs.

Oddly enough, all the plots I have seen of cost increases don't show a massive skyrocketing of costs since the profit caps were introduced. If anything, they have been somewhat reduced.

However a reckoning must happen at some point, health care can not consume the entire economy's efforts.
