I think the biggest systemic issue in most places is that most people don't actually know how to train people, including most senior staff. Very few people are actually natural trainers/instructors, so they have to be trained in how to train, and the expectations that they do so has to be part of company culture as well as time baked into the workday to do it, because it DOES take time. It pays off huge in the long run but it can be hard to see the forest through the trees if the management themselves don't know or understand the value.

As much as I hate corporate jobs they're generally better than small companies about having a formalized training program. It's a shame because there's so much garbage in corporate culture that a lot of small businesses don't want to implement the good with the bad.

One thing I've seen over the years is that a TON of businesses have NO IDEA how to be functional. It's a person that started in their garage and managed to grow and they just do stuff, and keep just doing stuff and hiring more people to do stuff and quickly outgrow the garage but don't introduce sound business practices that you need to run things effectively. It's crazy how many businesses are like that.
