Well it’s certainly not a Big Cut to SS as in the OP title. This obscure and seemingly random factor probably made SOME sense I suppose, when looked at a long term/10,000ft view from a “health of the economy” point of view, but still makes little sense to fix an entire lifetimes starting point on a seemingly random age. The AWI is used to change the multiplier of every single year counted towards ones benefit calculation. In essence, a running inflationary increase that adjusts all previous years to equalize the lifetimes earnings to today’s dollar and lifts the maximum amount of SS that can be claimed, AND how much the salary amount that is taxed can go up 2 years later. So expect a small or maybe reduction in the max SS premium for those w*rking in 2022.
However, I don’t see anyone experiencing a significant reduction in (projected) SS, more likely a smaller or no increase over what there would have been had there not been a lockdown. The larger your benefit above the 2nd bend point, the larger the reduction.
While those born in 1960 are the most affected, the reality is everyone born in 1960 and a few years later are all affected. Basically, if born in 1960, there is a smaller or nonincrease to ones SS (besides COLA) from then on. The die is cast. But if born in 1961 or 2 even, that smaller increase in multiplier is still there, and could in fact be even worse if there is any kind of wage recession the next year, as then two or 3 years years in a row could see lower increases, compounding the flattening of the increase curve.
The real irony is that if this bailout causes inflation down the road, then then those born in 1959 and earlier would see larger net increases in their SS checks (which compounds of course) so two people with identical MAX SS earnings and 35 years counted and claiming age date could see the 1959 born person having a $100/month (or more I suppose) larger check than his financial twin born in 1961, forever.
THAT is the claimed $25 to $80k lifetime reduction claimed in the original article. Though, I think their percentages are too high. And as mentioned in the Boglehead discussion, that effect is there from then on. It just gets lost in the long term smoothing of year after year changes, compared to the easily measured 1960 & 1961 cohorts.
But then, SS calculations never made much sense or were ever fair. I have made or exceeded max earned income earnings for 38 years plus 4 years under max. Lots of overtime that increased uncle sams coffers. Only 35 of those years count towards SS. 2020 will be my last year that exceeds max and because I am 62, and my AIME is fixed, last years and this years increase to my SS will be on the order of $20/month, for which I contributed around $18000 to FICA & Medicare for just those 2 years.Hard for me to get worked up over a smaller than projected increase for others that, say, ERed at 50.
