The employees shut inside coffins - Stephen Evans

“There is no document of civilization that is not at the same time a document of barbarism.” 
― Walter Benjamin

It may be that the article touches the subject in a superficial and whimsical way, but in my perspective this kind of "business" practices are very telling in the sense that they are one more manner in which the utmost commodification of everyday life shows itself.

One can argue that suicide it's the ultimate act of resistance that workers are forced to do by a relentless pressure to be competitive, effective and productive from the labor market. If the exploitation and oppression extends to every aspect of a person's life and labor and leisure are no longer separate spheres and don't have separate spaces in a given society thus the reification process is so complete and profound that it causes individuals to  kill themselves, to make the ultimate act of resistance against the social relations of production that dominate their society, if theirs symbolical existence as human beings is denied by contemporary capitalism and its dominant ideology, then they denied their physical existence as well.  

But how do capitalism deals with this symptomatic act of its own effects in human beings?

It converts it in a effectivity/productivity problem and develops workshops to try to "fix" it. The process has gone as far as that even death is a commodity, one that can be sold even to the subjects whose death is being dramatized. Using their own death to scare workers into not dying in the name of productivity.

Not to say anything about the ex-funerary worker that found a new niche to explode. What a entrepreneur he must be. 

 It's also very telling that this happens mainly in one of the Southeast Asian tigers, one of the countries used as an example of successful capitalism-based development, if this is what it looks like that's very worrying.
