I haven't a clue what your question means. But what actually happens in SS is that your inputs (lifetime contributions) are less than your outputs (payments), so the system is slowly spending itself into oblivion. Now if you had put the same money in a private account that accumulated interest or returns this would not be the case. But in the case of SS current income is paid out and not such compounding takes place. Why anyone is surprised that some States tax this income is beyond me. they tax anything they think they can get away with. Pick your living situation based on the tax burden that matches your life style. this is only on factor.
