Honestly as an older git.
The whole idea that the younger generation is not interested. Is hardly a new one unique to gen Z.
Pretty much every generation since the 1900 has been accused of this.
The only difference is how much change in culture each generation has had to face.
Honeatly pre 1900s. One generation did not face much change from that of their grandparents world. Since then each generation has seen more change then the last. As technical groth has sped up notable even in my 50 plus yeae lifetime. The changes have been notable.
But each generation. As they age a % develop interest in things to a higher level. Little indicates gen z are any different in this.
Politics not supporting younger voters is not the same as young voters not being political.
Your statistics are not a valid criticism of gen Z. But of our generation and our failure to support the end of FPTP over other issues.
A 2-second look at the fucking fiscal mess we as a generation have left by voting for property prices and removing support for the higher education costs we had. Makes it pretty clear why those opinions exist. They are not a rejection of politics. But a rejection of the politics pushed by our generation of voters.
