I am describing a comparison between two situations:
A government (e.g. a communist one) that takes all the property of everyone and re-divides it.
A government (e.g. a welfare state) that taxes some of the property of the rich people but lets them keep most of their property.
I am looking for a general noun that describes, in the second situation, the fact that people are allowed to keep their property. It should be used in the following sentence:
The second government satisfies the partial ___________ principle, which means that each person is allowed to keep a part of his property.
I am looking for a word which emphasizes the fact that they "keep" and "remain" with (some of) their current property
Maybe "persistence" or "consistency"? Something similar to these?
