The FED is not trying to push unemployment, they just accept it as a cost to curb inflation which is always enemy number one. Interests rates and unemployment are correlated; you make borrowing more expensive, people invest less and become more conservative, often by trimming.

EDIT: Fixed correlation sign.

Same energy as "the gunman wasn't trying to push violence, he just accepted it as a cost of firing his gun wildly into a crowd"
