$1.35 Trillion is >33% of 2021 federal tax revenue. That is not nothing, but yes, if you spread it over 50 years, it would only be like 1.14% of annual tax revenue. But one problem is that's just statewide pensions. There are also plenty of municipal and other pensions that are also unfunded and then the federal government itself has a $5.3 trillion (net present value) of shortfalls of social security over the next 75 years. So put just the statewide pensions and social security shortfall for the next 75 years and amortize them over 75 years, and you end up with annual payments that are 5.6% of tax revenue. It would not be painless to cut out 5.6 percent of tax revenue from spending or to add 5.6% to tax revenue. But of course, we're not on a sustainable spending path right now ignoring those issues. so we'd have to get our annual deficit back to something around 3, maybe 4% on average, and then find a way to cut another 5.6% of tax revenue out of spending.
So even if you say 17 medicare recipients, 17 pensions that aren't state wide, you still end up with some pretty painful adjustments even if you assume we flipped a light switch tomorrow and started acting prudently regardless of the political realities. Of course we're not going to start acting prudently until we have no other choice and we're not going to cut medicare spending to match revenue. Doubt we're going to leave non-statewide penions out to dry while bailing out statewide pensions, but it's at least possible.
