Dennis Prager makes worlds of sense, which is why the Left hates and fears him. Yeah, yeah "PRAGER U IS NOT A REAL UNIVERSITY," whatever. It is in the sense that he is spreading the word of...common sense. Works for me.
POP CULTURE - gives youth a fantasy life that they cannot live up to. They try their hardest being Try Hard Wanna-be's. There is also this massive "cult of friends" put out by the left, where friends are sooooooo important - they are not! Everyone wants to be a rock star as that song goes, proving how empty the youth are to begin with. All sad but true and many will never admit it. How about you?
I not a fan of Dennis Prager. As for why young people are often unhappy I submit it is the nature of the young to be dissatisfied with status quo. We have created a paradox whereby the youth today do linger and languish far too long in the feathered nest while every fiber if their youthful bodies is nagging at them to get a move on - make their own lives better and in the process blame the older or previous generation(s) for their angst.
It's tough to be a young person - all you know is that you really don't like things they way they are but you haven't a clue as to how you can or will make any meaningful improvement of the proverbial world.
Certainly all of us old foks have not forgotten how driven were were - we just didn't know what to "drive" toward so we looked around and decided to make a binary judgement...old people, old ways bad...our way better...
