Interesting point about class signaling, but it doesn't explain Peppa Pig (or Bluey) showing a more healthy approach to teaching emotional regulation. The English certainly value that same kind of behavior after all.

Kids learn really fast that they can't just act out with their peers for fear of rejection by the group. It's extremely strong and parents need to teach the other half of it, dealing with negative emotions WITHOUT acting out. I feel like DT does a disservice here.
