I think that's pretty arguable, and I'd want to see actual research. Certainly kids today are wildly more likely to embrace Stuff that Pisses Off their Elders than at any time since the 60's counterculture revolution. Think gender fluidity and pronoun choice, body modification, protest culture, rejection of career paths, embrace of the "neuro-atypical" as routine personality types... all that seems qualitatively but inarguably higher than when I was growing up 30-40 years ago.
