If it actually improved the workforce and made people somehow more productive, then it would be more understandable. Maybe the company gets some sort of Brownie Points to show on their record that they offered such "training". All the while, those folks that present these programs are laughing all the way to the bank as they congratulate themselves for making all that money for their con job.
They should carry out some measurements and see what impact they have relative to the expenditure. Or then again maybe they don't for precisely that reason! Lol!
