Well, that 2% was still being credited to your SS benefit calculations (and the SS trust fund, IIRC), so it's not like you were borrowing against the future.
It's just a temporary tax cut that was passed for a year, extended for a year, and then not extended this time. So it's not a tax hike compared to what you've been paying for most of your life, or what you'd normally expect, but it is more than you paid the last couple years.
And yeah, I'm agin' it. Contractionary policy is contractionary.
