I mean... as a millennial I get it. But as a British person I can tell you that most of the stuff you're talking about are global problems - certainly inflation and barriers to education are.
The biggest rebellion is happiness (what happiness we can grab anyway,) - every inch of joy, equality, fairness, is a victory.
The world has always been harsh, cruel, hard. The world's ended before, plenty of times.
That's not to belittle the struggles of today, but tomorrow will come - in some way, shape, or form that we can't even imagine right now, tomorrow will come. (I'm an eternal optimist - albeit one with Depression! Lol.)
