Did you not see my post above? You ever work with stupid people that would struggle with 2+2 and much less other basic concepts.
There are people that I wouldn’t rely on with holding a pencil much less be competent at doing a job, and believe me they try to work.
I’m sure there are plenty of jobs for them out there for such people, but hardly many of them will be “good”.
Edit: if everybody really could get a better job and all of a sudden did, what do you think that would do to small business and places that rely on paying minimum wage? They would have to raise is just to attract people to “worse jobs”, which would lead to increase in prices no?
