Culturally I can see it.

Economically I can't.

The silent generation and greatest generation didn't track that way in the UK.

The similar studies I've seen show the boomers lurching to the right and older generations being basically consistent post war.

This also tracks with the "post war consensus" between parties in the UK and essentially identical Keynesian economic policy until Thatcher and Regan in the US.

Being part of the post war rebuild and remembering the new deal that generation remained essentially Keynesian.

Boomers went full on Ayn Rand and hand of the market trickle-down economics. Gen X get to hide in the noise, millennials are consistently against trickle-down economics having come of age in cut backs and austerity. Even favouring full on socialists. Gen Z basically track with millennials economically.

The culture war might make it seem like we all track right over time and the millennials are different to zennials. If anything Gen Z being clearly more outspoken on environmental issues is making some millennials I know more liberal rather than tracking to the right.

While some millennials don't like being told the homophobic jokes they grew up with in sitcoms are wrong. Most seem to accept that and move with the times still.
