The fall of the Tory party

Is that necessarily the case though? It's always a movement relative to the mean - so if society gets more progressive due to young people having those views, the effect (relative shift to the right as age increases) would be visible even if views just didn't change....

I’d put corporate structures in there too. A lot of people work in those organisations that are right wing AF. They use marketing to appear inclusive or progressive, but those structures are anything but left wing.
A lot of people find themselves in this environment in their 30s and they foster a more right-wing mindset. I know I was swayed to an extent when I was chasing corporate bonuses.
I think it goes hand in hand with homeownership.

For me this has to be a story about home ownership / generational wealth distribution. Owning your own place and "enjoying" a few years of house price inflation turns you into a Tory. Has informed all of the blue team's housing policies since Thatcher.

except that doesn’t seem to be working any more.

I think he is missing concern for the environment as a potential factor.
