Stop in for a cup of coffee
Regarding SSI bear in mind the fedril gummit is like Wendell P Wimpy who would gladly pay you Tuesday for a hamburger today, then when Tuesdee comes he's nowhere to be found. And they can keep you working a little longer, a liiiiittle longer, a liiiiittttttle bit longer, to get a little more, 'til they carry you out in a box. SSI whitewashers claim the fund is solvent with trillions in treasury bills backing it up, but there's nothing there; a T-bill is just an IOU from the gummint to the taxpayers, payable by the taxpayers - an IOU from U to U. Realistic prediction: Payout will diminish by 13 to 30% by 2030. So you could wait longer to get a little higher percentage of a lot less money. It's a Ponzi scheme and the pyramid's base is rotting away.
