Surely there must be some people who are in the middle, who would gladly pursue training if it were paid for and if time were made available for it by their employer. Consider, for instance, those people who have significant family commitments who cannot work more than fifty hours each week without suffering some hardship (maybe they have children or elderly parents or both). Just because you don't have free time outside of work to learn new things does not mean that you wouldn't want to learn new things if you had more time.
