If you have a bunch of companies trying to keep their shit together while barely able to make their product and then someone kills himself simple because the situation is no longer worth living - then it is a sad thing.
If the product is one of the most successful things in human history the suicide is a design goal.
If we don't stand up to it and at least voice our objection we will all be treated like that eventually - regardless of corporate success or personal productivity.
The only other role is that of the psychopath pressuring those who do the work in order to meet the suicide quota. If you don't meet the suicide quota your workers are not working hard enough or you are paying them to much. It's simple business logic nothing personal.
It applies to low wages for illegal immigrants too. Once they're in our country, we feel responsible for them. Before they got here, we don't care at all how little they earn. Some people even go so far as to want to kick them out to save them from earning low wages. Really it just saves us the guilt but makes it worse for the individual.
And if someone lives on corporate campus but commits suicide off of a bridge in town, not counted?
Note that one of the attempts catalogued on Wikipedia states that one Mr. 刘 "threw himself from the sixth floor of a dormitory building". That would tend to imply that the statistics cover the workers while they're on or off the job -- the statistics are for suicide attempts on campus, but the employees live on campus.
And that would tend to imply that the appropriate comparison is indeed "how many people commit suicide anywhere?", not "how many people commit suicide in the office?".
