I genuinely don't know if even "can" is applicable to allpoor people in this context. A person who has a similar background but ended up with a chronic illness preventing them from working... that dream of working for 200k/yr is impossible.
Do you watch Tasty videos on Facebook with their two hands and three ingredients and four steps and think "What useless advice - what about people with no hands! How dare suggest they can make bakeless chocolate brownies!"
I think the "can" is applicable here and can think that even while acknowledging there are people who can't physically work. I don't want to put words in your mouth, so I'll ask: is this the only reason you object to using the word "can"? What would be more accurate in your view?
