How much interest are the banks currently paying on $2K? If you got a lump sum locked away for a year: lucky you. How about the interest on $170 saved on a monthly basis?
Probably the interest is so small it's barely worth the effort spent planning and budgeting. Getting $2K back is a nice bonus if you've already been ok with your pay cheque.
Every person in the US owes a huge amount of money anyway. How significant is the interest on $2K compared with that? Think of the amount of taxes you pay each year just to pay for the interest payments on the national debt. You would do better to vote for politicians who will both cut spending and increase taxes and try to reduce the debt.
