What he meant was people differ in their abilities and one should select the proper person for the job. The difference between the "first class" and the one unsuited could be dramatic. Today we know all computer programmers are not equal and the best ones can be as much as ten times better. Also every job should have rest breaks so that the worker is not tired.

While this principle has a certain logic, in practice it has two obvious deficiencies:
