If landlords had solidarity with tenants they would not be landlords.

I mean, if you're collecting rent...

We've just got layers of landlordism now. Everyone can be someone else's landlord. So we're all... uh... in it together? Except when it's time to eat shit, at which point there's a hierarchy again.

Like in this scenario the landlords are no longer getting passive income with no labor right?

Sure they are. They're still landlords and they still want to get paid. They just don't want to pay their mortgage notes.
