SSA already “means tests”.....especially for those who try to recoup what they paid in at 62 for what they have already paid. SSA also monitors income to quickly assess penalties for making too much to dock you more for your Medicare (Part B and for Part D) regardless of whether you have a great retirement plan that doesn’t expose the SS one cent beyond that same exposure they’d have with its recipients still on SNAP (yes, they have that for single oldsters, too), EITC and all the rest.
