The system can't want anything. It isn't even really a "system" in any meaningful way, in the sense of being a unified entity working towards a common goal. US healthcare is just a bunch of disconnected people and organizations pursuing their own interests, often in conflict with each other. Any major improvements will require changes at the federal policy level to better align incentives with desired outcomes. This is hard because we collectively can't even agree on the desired outcomes or how to measure them. I mean at a high level most people think that everyone should have convenient, affordable access to high-quality care but once you get into specifics everything gets complicated and making trade-offs which disadvantage some voters is unpopular. Like should we spend $100K to give a terminal cancer patient another month of life? Should surgeons make $700K per year?
It's easy to complain and cast blame. And we should certainly cut out waste and abuse where we find it. But that won't significantly move the needle on overall system costs. The problems are much more fundamental.
