This is the real solution. Businesses hate training new employees and then complain that no new employees know what they’re doing. There is a first mover problem where any company who invests in training can be cherry-picked by a second company who simply raises wages (because they save money on the training budget).
This can create a so called “skills gap”, where you need skills to get a job but no one is willing to give you a chance to practice those skills. Certifications try to fill the gap but do the bare minimum. We need job training schools funded by each industry. Ideally larger companies would also be forced to hire each graduate above a certain skill level.
