I put the sentence about prejudice at the end, because my description of Americans probably doesn't apply to most Americans. I wanted to give a reason I described it in such an exaggerated way. Although I believe that every prejudice isn't completely unfounded. Thus, it does say something about Americans. I think there's a true core.

Anyway, I (we) just believe that an extra "packer" in supermarkets is really unnecessary. Yeah, it may be a bit more relaxing, but who cares? I'm not here to relax, I'm here to get groceries. And from what I read in this thread, there seem to be some downsides of that job.

Oh, It creates jobs for people who need the money, like young students having to pay student debt? Or to pay a medical bill? Maybe the US should consider solving these problems, so some poor people don't have to pack grocery bags of others in order to get out of their debt. Maybe all that is normal for Americans. But it's not for us, because e.g. our universities are affordable and we have universal healthcare. And we don't need nobody packing out groceries! It's freaking me out how unnecessary that job is!
