Warsaw is "returning" public housing buildings to heirs of people that formerly owned part of the land they were built on, or claim to be heirs. They couldn't have inherited the buildings, though, because those were built later by the state.

The lucky new owners force the tenants out using cruel dirty tricks.

Even if one adopts a heartless 100% capitalist point of view, giving the buildings to them is unwarranted and unnecessary. All they are entitled to is the value of the land they have a claim to.
