[EDIT] sense 5 in Webster's 1913. Apparently it is, or at least was, a US usage.
5. An assistant in a shop or store. [U. S.]
Contrast that with my FAANG job I have now. The pay is phenomenal. But it basically swallows my life. Between the long hours, weekend on-calls, constant churn, all for a customer I've only spoken to indirectly via a project manager. It's hard to feel like the work you're putting out is really making a difference in anyone's life. With covid and the lack of direct human contact as well, I'd go so far as to say I'm practically pushing commits into a void everyday and getting paid for it, there's very little if any feedback for my work. First-world problems, I know. But if you took away the pay differences, I know which job I'd choose in a heartbeat.
I'm not about to complain about my software development job in the US, but if not for job insecurity I'd rather clerk (not even own) at some small retail shop in Europe. And yes I've done "menial" jobs—take away the stresses of US healthcare and retirement systems and worries about your kids' ability to pay for school, add European amounts of time-off, and lots of those jobs are pretty damn great, actually, job-insecurity aside (which is not a trivial thing, I grant—point is about what's "fulfilling" or satisfying in a job).
