The New Frontier: Collaboration Over Competition
These systems aren’t just buildings with beds—they’re ecosystems tackling societal ills. Looking ahead, their focus will shift from “more beds” to “smarter care”:

In a nation where healthcare debates often divide, these titans remind us that scale, when paired with purpose, can be a force for universal good. Their stories aren’t about corporate rivalry—they’re blueprints for a healthier, fairer America.
