There are economic reasons behind it. My company used to invest a lot of training in the employees because most employees were working for the same company a very long time, more than half till retirement. I got a lot of training ~ 20 years ago as a new hire, while the new hires today get almost nothing, not even the bare minimum to do their job. Why? Well, a few weeks ago I had a meeting with a team from a very well known IT company for a project and they all expressed their amazement when they heard I am working for such a long time in one place; people now stay 3-5 years in a company and move on. Why train them, to make them better for the next job?

Companies that invested a lot in their employees paid less than companies that had no such expenses, so it became common to have a new hire, spend 3 years on trainings and leave for a better salary. This competition pressure made us adjust and move the training budget into salaries.
