They can maybe get jobs for Microsoft and call people up to tell them they've noticed something is wrong with their computer!!

“maybe, just maybe”

“One can dream.”

You’ve either used these sarcastically, or accurately. I think you’ve done the former, but the truth is the latter.

I am absolutely serious. Any employment has opportunity costs: a person who writes and sends out cold call spam e-mail for 8 hours a day is a person who could be spending those 8 hours on something else, but isn't. Yes, switching jobs is not very easy, and it's stressful but humans, thankfully, are not (yet) a species of highly-specialized individuals, with distinct morphological differences that heavily determine the jobs they potentially can or can not do.

So I was right, you did use it sarcastically, since you are still naive
