No, you've been rated down for a reply that does not actually address the comment the parent poster made.

Your comment on Social Security accounting (which is correct, as far as I know), has no bearing on the parent's observation that FICA tax doesn't scale linearly - because it is capped at a certain point.

The essential nature of Social Security accounting is such that FICA tax is unrelated to FICA spending. At the moment, much of your FICA tax is spent on general fund items. In the future, much of your income tax will be spent on FICA items.

Thanks for explaining!

These numbers are based on expenditures; to cap off the FICA portion of the receipt despite actual spending would be misleading.
