We should be glad to have this, especially in these times. One problem is that people often leave the company after completing the apprenticeship and they even get encouraged to switch employers. Every healthy company I worked for didn't like company hoppers and tried to retain employees. Some departments always have some fluctuation, but it is one of the best quality markers for a company in my opinion.

But as you said, lateral entrants might have a difficult time since there is a profession for everything. It is a transient education system though. Even if you only got the lowest kind of basic education, you can do an apprenticeship to get access to university or any higher education. Some people need some time to find motivation.
