In the past I read something like this:
If basic expenses for family went from 100€ to 200€ but its wage went from 200€ to 400€ it can expend more than before.
Weighting the costs of living in state X, in the median wage in state X, is the best way to compare state X's COL with COLs of other states.
I assume that weighting COL in MW particularly is better than weighting COL in average wage (AW), because, although there are few families with extremely high wages, their wages bias AW extremely upwards, while MW is less effected from such extreme cases.
Is weighting COL in state X in MW in state X the most accurate way to compare that COL to these of other states?
