Whoever says that surplus is a fiscal responsibility, either has no idea about macroeconomics or is a fraud or both.

On the other hand controlling the deficit is not a light topic and also you have to have control of your currency (do you hear eurozone citizens?).

If you know what you are doing, you can for example, control deficit with inflation (even if that sounds odd to some people). For example if you borrow today one billion € and you have to pay it off 20 years later, the value of the one billion would not be the same after 20 years because of inflation and you could pay it easier. I simplified it, but do you get it?
