What do you mean by investing though? I think these days junior people have to just invest in themselves and learn by working right? It’s also hard for companies or managers to spend more on them when they can leave at any time, which means all that effort training them will just benefit some other employee.

I’ve noticed younger generations are especially a lot less loyal, probably in response to abusive and exploitative employers and horror stories. But the downside is if employees have less loyalty themselves, then even caring companies and managers cannot justify being loyal to them. They end up losing that time invested and learn a hard lesson.
