Sadly Enough I used to work there.... but then again I was just outta high school, 18 and getting payed about 15/hr. So I guess If I look at it that way it worked out for me.
All in all, TSA is here for security. As immature and retarded some screeners (now "officers") are, they do make the vast majority of passengers feel safer.
...Hence I sad "feel" safer.
Enough Said.
