First of all, _basic_ rights should be afforded to _all_ humans. That's not what the discussion here is. The discussion here are non-basic rights, like the right to enter a geographic area without restriction or the right to state welfare.
You saying "job/role" is where the argument falls apart, because job and role are not the same. Yes, I absolutely agree that people who fulfill roles in society should be afforded protection of that society.
There are roles in society that have nothing to do with your job: neighbor, volunteer, person you ask for direction on the street, parent, parent of your child's friend... Those are also the roles that typically have some form of emotional, spiritual and cultural work associated with them.
Refusing to fill those roles and filling only the role of "high-income immigrant" isn't necessarily a net positive to the society and should not on that fact alone be provided permanent residence.
I will say however, I think parents of children that attend public school in a country should have almost automatic PR. Not fully automatic, but 99.99% of such cases are net positive, much more than high-income immigrants.
