That's only an upside if there are better alternatives for those people. If there are only worse alternatives, then obviously it's worse

I've worked in call centres a couple of times and found it depressing, but I've also worked in a restaurant washing dishes on sixteen hour shifts. To be honest, call centre was better

Where is the line of what you find acceptable then? As long as there's no a alternative anything is ok?

Like I get what you're saying but some work is just cruel.

Yes, and some work is crueller than others.

What I'm saying is there's no upside to just getting rid of an option

I outlined the upsides.
