Most online classes are just really crappy small scale closed MOOCs and most people are incapable of profitably completing a MOOC. Those who can, perhaps 10-15% of the population, are the same people who could have done reasonably well given a textbook and told to complete all the exercises and the test is in three months. Learning materials are not the limiting factor on learning.
