Obviously we'd offer them help and if after a while they still wanted to commit suicide it is better they do it were it will either minimize its impact on the economy or benifit the economy ( depending on weather or not the organs would be harvested but that's another issue ).
Life is to precious to throw away. Its not like money or food that you can throw away and get in back or get more of. Life is a one time thing that could impact others in so many different ways. One of my friends just the other day committed suicide and the impact is horrific. Others are now in pain because they lost some they cared for. Now what if that leads to someone else contemplating it and so on. Suicide hurts everyone around even if there not the one who committed it.]
