I think the issue here encompasses several factors: 1) you seem to be conflating the kind of moral panic driven legislation which has historically always existed with a silencing tactic aimed at dismissing youth-driven cultural criticism and 2) this meme screams low hanging fruit, appealing to the emotions of young people for whom having their phone taken away is like torture while also engaging in the, at the moment, very popular denigration of older Americans as being out of touch and dismissive of continuously worsening societal issues. Point 1 is understandable, as criticizing new things as being a corrupting influence on young people is as old as dirt, as is the propensity for the powers that be to dismiss cultural and material criticisms of the worsening state of peoples' lives in hard times. And while they may exist as a part of a shared rhetorical and ideological ecosystem, their relationship is too complex to be purely causal, as your meme seems to be suggesting.
