Why Don't Training Businesses Scale?

It is not that training companies don't scale up. It is however a valid point as far as behavioral /soft skills training is concerned. It is not the case with technical training though. Take software training companies for example. Some of them have grown real huge. In fact, there was a time in the 1990s when they were minting money left , right and center, before formal academic institutions spoilt their party by coming out with the training program in their own curriculum.
