The person who names the sacrifice rarely carries all of it.

The person who declares that a sacrifice must be made is usually not the one who will feel most of it. The word we does a lot of concealing here, spreading a cost rhetorically while it lands unevenly in practice, and the announcement can even feel noble to the person making it. Naming a hardship is much cheaper than bearing one.

When sacrifice is being invoked, work out concretely who pays what. If you are the one calling for it, take a visible and disproportionate share, or stop calling for it. And if you are inside a group being asked, it is entirely reasonable to ask how the cost is distributed before you agree that it is shared.
