Why might a country choose to run a deficit instead of balancing its budget, and is it always a bad choice?

I believe that we should balance the budget because we need to provide resources so that people do not starve.

A country would balance its budget when they are in trouble and must spread its resources throughout many categories. I don't think it's always a bad choice but it would be in America because we have many items that would be over-funded on a balanced budget and would underfund many vital programs.

because a country might have most of there profits from that area of that budget,so more money is used in that sector,and it is not always a bad idea just as long as the country has other modes of production.
