Social welfare needs to be handled at the same level that mobility exists, because otherwise all destitute people will bumrush the nearest jurisdiction that is giving out generous welfare benefits. The issue is most often seen at the city level (e.g. Bellevue “encouraging” homeless to go to Seattle), but more generous policies like housing-first will need to be federally administered to prevent the most generous states from getting bumrushed.
