However - the kids will be replaced by other kids.
'Social Protest' - I believe is actually a form of normal rebellion.
As kids grow and they come into their own identities, at some point, they have to rebel against something. Kids who are abused rebel really early in life. Kids with their own identity rebel in HS. A lot of 'well-raised kids' don't rebel until University - and this rebellion takes a more intellectualized form.
'Youth in Revolt' is perennial, it's metastasizing now because of the possibility of outrage.
That said ... Baby Boomers were considerably more outspoken than their progeny so perhaps whatever comes after Gen Z will be more chill.
