Well, yeah, but young people are by definition immune to future shock, having experienced little of the future so far.
Aren't you in an upbeat mood today. I'll try not to spoil it, but merely note in passing the strong correlation of age with the sort of sourness we're talking about. The most dissatisfied people in America today tend to be the oldest. Don't ask me what my weekly conversations with an 84-year old Atilla the Republican are like these days. That'd spoil your good mood fer sure.
Enjoy it...
