Fostering Students' Creative Talents - Why Educators Encourage Creative Suppression

I came across this post on IG, 9-Year-old Who Got in Trouble for Doodling in Class Now Has Job Drawing On Restaurant Walls, and it immediately caught my attention. I've always been the teacher, the person, who've witnessed year after year the down play of that one student that was the talk of the lunchroom - "All he ever does is draw, I can't get him to do any "real" work." What has the American school system done to aspiring, developing creatives? Why are we as educators so quick to suppress our scholar's innate talents? I ask these questions facetiously, knowing my answer - standardized testing is the cancer that kills creativity. Bold blanket statement, yeah I know. A larger scale discussion should be had - the notion of differentiated public schools sounds promising, but not likely.
