I think this is more than a bit naive. Companies have a wide variety of values. Some certainly do the best they can for their hires as they’re able, others very shrewdly extract every bit of value they can. Most fall in between in a variety of ways.
But assuming the best intent is just plain ahistorical. We’re only a century out from when companies routinely hired armed security services to threaten and ultimately murder people organizing to get their share of what wealth they created. That’s widely understood to be excessive now and those of us in privileged career positions take that for granted, but I think it’s worth remembering that some people still have that to survive and most of the rest of us are navigating a kinder gentler version.
