While this is only anecdotal evidence, I have gathered from conversations with people not in the workforce, while being well educated, and the lack of motivation wasn't coming necessarily from a lack of ethics but more from an actual understanding what their work was contributing to, and not desiring being part of an activity they disagree with the finality of it, or at best consider it a waste of time and energy.

Again, only personal conversations with some friends and acquaintances, nothing statistically representative, but definitely show there is room for looking deeper at the root this trends before labeling people as lazy.
