Where did 2% of Your Income go?

So I keep seeing articles and reports on how the payroll tax has been hiked by 2%, and I wonder why it is being reported as such, because it isn't a tax hike, it is a return to the rate that we had before.   The rate for payroll taxes has been 6.2 % for many years, since 1990.  The decrease to 4.2% was a temporary measure for 2011 and 2012.   The administration in an effort to increase workers take home pay, during a weak economy, reduced the payroll tax by 2%, so instead of those funds going towards social security which is where they normally go, they came home with you.
