It means the education system is design to pump out workers rather than thinkers. Taking this to the logical conclusion, why teach science, history or sport in high schools? Low ROI. Stuff that!
Why not make the coding bootcamp start at kindergarten. And why not let parents pay for such schools so they can choose the best ROI for their kid.
If those "thinkers" were really contributing something valuable, that will show up in ROI. If you don't agree with that measure, how do you propose to eliminate completely useless classes and make space for better alternatives? Do you just assume that any classes that are part of the status quo must be valuable?
So do you have a proposed improvement? I think taking schooling time away from history and sport and putting it towards coding would make us more, not less, likely to solve climate change.
