> Can't you make the same argument at organization level? I'm sure many Amazon warehouse workers would agree.
Honestly, I think you could. Actually, this is something I was thinking about a lot in context of employee rights. Making workers happy - good office conditions, paid leaves, healthcare benefits, regular schedule, etc. - is a cost for a company, and creates inefficiencies that, if eliminated, would let the company do more while spending less[0]. So many companies are indeed happy to make employees as miserable as they can get away with[1]. Enforcing worker rights is purposefully introducing inefficiency, in order to avoid the market optimizing away all human values.
So let me rephrase my original point: you can get away with much more efficiency in companies than in countries without making a lot of people miserable.
