"... Costco does not hire business school graduates—thanks to another idiosyncrasy meant to preserve its distinct company culture. It cultivates employees who work the floor in its warehouses and sponsors them through graduate school." https://www.bloomberg.com/news/articles/2013-06-06/costco-ce...
Their job is to make money; they don't care, and they are not paid to care about anything else.
Now... the question is, does someone with a different background care about the company vs making money in different proportions to the set of 'expert business administrators'?
I posit that yes, someone with a different background will have different priorities to simply 'make as much money as possible right now'.
Maybe even a chef.
