I mean, if you make more than $400k a year this is bad news, but anyone making more than $400k should be able to FIRE regardless in short order. Moving the payroll tax gradually from 12.4 to 14.8% over the next 24 years probably doesn't move the meter much in terms of reaching FIRE for anyone making a more average salary with most folks hoping to FIRE in less than 10 years (plus, offset by increasing the SS benefits by a similar amount). However, I'd argue this does impact FIRE if there's more certainty on SS solvency. Of course, as shared earlier I think this is just an exercise in what ifs. It won't get approved, and would be attacked for years if it somehow does get pushed through in the future. Still, I'd hardly call legislation like this meaningless or of no impact to FIRE. Having more certainty in SS (if possible) would make cfiresim much better at projecting. For instance, 4% WR on a 50-60 yr retirement is just north of 80%. You plug in SS and the success rate is 100%.
