I think it makes sense for them to be decoupled on some level, but maybe not totally. The danger on one side is falling into a sort of hedonic treadmill issue where the poverty level defines a standard of living that is so generous that it ceases to be a measurement of hardship. The danger on the other side is fixing the poverty level at some static level that doesn't take into consideration inflation and other changes to the environment that people actually live their lives in.
