Compare working at Target to working at Costco. Target is a “working retail sucks” job, whereas Costco is a “retail can be a career” job. At Costco, you do a wider range of jobs, like driving forklifts, selling memberships, etc. At Target, you just restock shelves and occasionally help customers find stuff. Target wants disposable employees, so its onboarding process is streamlined to narrow roles (i.e. perfect for students looking for a part-time job).
So while those jobs may not have been created with that in mind, that’s how they’ve been optimized. Most retail jobs are intended to be disposable, which means they’re targeting the low-end of the market.
