Blue collar vocational training is more mature than software development vocational training. It's typically taught by people who have professional experience, and there may even be an apprenticeship period where people are explicitly learning from an expert in their profession while on the job. In software, on the other hand, we often have most training being taught by professional academics who do not understand and are not qualified to teach the parts of the job that don't have a straightforward academic analogue. Combine that with a business environment where things like budgets and cost control are often only theoretical, and all but the most gross liability for defects due to poor workmanship has been waved away by EULAs, let it marinate for several decades, and... yeah. Not only do people not know these things, but I'm not entirely clear on how or why they should be expected to learn them, either.
