The speaker is Simon Sinek, who, among other things, is a "leadership consultant" and sells books and courses on how to make people work better. It's suspicious that a man whose livelihood revolves around being paid to solve problems in the workplace is telling us that there's a big new problem in the workplace that needs to be solved. But the larger issue is that his speech is vapid, full of baffling generalizations, and, frankly, a little insulting. So at the risk of being a sensitive, self-entitled snowflake, allow me to explore how this random middle-aged man didn't "perfectly explain" anything.
Sinek says millennials "confound" business leaders because they're unhappy in the workplace, despite being given a "purpose" and lots of free food, because millennials are apparently kindergartners settling in for snack time. The first cause of this problem is supposedly "failed parenting strategies," although Sinek says those aren't his own words. Okay, then whose words are they? The words of someone who dedicated years to studying millennials academically? Or the words of some grumpy manager who's upset that his employees want a living wage? And how did someone else's words find their way into your mouth?
Also, hey, please don't casually assume that my parents were terrible. Kind of a dick move, man.
