You can run a moderate amount of deficit without anything bad happening, and governments can do it indefinitely. HOWEVER, the amount you can run is not unlimited and can collapse the system if it gets too high. So you should be very careful with how much debt you are actually carrying and how much you add to it. Also you need to be careful because the amount it costs to carry your debt can fluctuate.

The same is somewhat true for corporations as well.
