I'm sorry you're being down-voted, because the frank truth is... you're exactly right. To a first approximation, 0 companies really "care about their employees" in any meaningful sense. Work is simply a transaction arrangement, where you trade some of your time for some of their money. And either party can (generally) terminate that arrangement at any time, for any reason.
That's simply reality. One can choose to accept that reality and live accordingly, or they can choose to live in a pollyanna'ish world where one doesn't have to take personal responsibility.
