They are deporting people because their job doesn’t pay them enough?

Yes.

Edit: Not only that. But when the state is the employer! (In a broader sense, at least, eldercare is regionally organized, not nationally)

So since Sweden is part of EU and Schengen, it cannot deport EU citizens on this basis. So they tried to import EU citizens instead to fill the gap (who did not speak Swedish like the people they deported).

It is the apparent inconsistency of the salaries being too low and too high at the same time which reveals what their intention is: racism. Do they think the salaries are too low? No, because then they would approach the public sector unions and say "we fucked up, here is your money". It is only too low for some people. For some people, it does not matter if they speak the language, have a job, or whatever. Some people just need to go.
