Reminder: Class Size Effect Dominates All Other Instuction Effects

 When producing industrial artifacts, doing things in batches is more profitable. The bigger the batch, the better. Everyone who doesn't buy in bulk is loading the economy up with a huge strain and making us all dramatically poorer.

 In shocking esoteric news, children are not industrial artifacts. Don't exactly come in standard shapes and sizes. Increasing the size of the batch of children you're instructing has catastrophic effects. A class of more than about four at once is a waste of time. By the time the class is 24, the kids will learn faster with the instructor absent than when they are present. Even a softling retard teaching themselves is more effective, due to a class size of one, than a class of that size taught by the greatest communicator who ever lived.
