All of those examples you cited are drastically different types of relationships, set in very different contexts, that absolutely deserve different terms of engagement.
>Do we now hate the rich so much that we want to impose that burden on them when they pay someone
I don't even know how to parse this. We're talking about companies of a certain size. I guess we have fully stopped pretending they are anything other than an appendage of the wealthy class, and have no other responsibilities to society.
One must have income or wealth, however.
That doesn’t mean the last company that they happened to work for owes them these things.
If you think people should be entitled to food and shelter, fine. But it should be provided by the state, not by a private business that was unlucky enough to make a bad hiring decision.
(And in fact, the state does provide various forms of welfare including unemployment insurance. I’d be in favor of increasing those.)
The horror!
