Your statement makes a massive assumption that there are people who have the skills to learn but did not get a chance. You cannot teach or train anyone to love math or programming and perform problem solving on a daily basis. Training is very expensive as someone with 0 programming language will take atleast about 500 hours to become good enough to work for a large enterprise. To train someone, you need a senior person to spend an equivalent time which means for a company that's a loss of 1000 hours. Nobody has that level of time or money and small to mid size companies won't exist if this becomes mandatory.

To bypass all this, get someone who has atleast got foundational knowledge from uni and can be productive within a week. Else look outside and give th job to right fit of a person.
