At least in tech, companies have already decided to make employees pay for training. You don’t see people doing leetcode training or side projects to pad their resume because their employers invested in increasing their skill set.

I get your sentiment but the employers already cut all the benefits out of the system when it comes to skill development. They’ll need to start adding back in investments to employee’s skills without any sort of guaranteed payback for a while before the average employee would extend them any trust
