You seem to be very passionate that the article is somehow misguided. However I, and a lot of others on this site have lived and visited large metropolitan cities all over the world. I can clearly remember seeing passed out men in suits in Tokyo and no where else in the world (anecdote). There are passed out people in other cities, but not businessmen in suits. The article clearly states that the photographers criteria was that the person was sleeping in a suit in a odd configuration. The article is interesting and accurate.

You will find drunk salarymen in the evenings yes but seeing them passed out alone outside is very rare in Osaka. Not uncommon on trains however.

Sorry I typed hastily, I’d only had first hand experience of it in Tokyo; my mistake; agree this is an more generic urban phenomenon.
