Arguably, there were different values in effect in the past.

There was more emphasis on values like: God-as-god. Country. Family. Courage. Integrity.

The newer values are more like: Money-as-god. Survival. Cats. Dopamine maxxing.

I may get downvoted for mentioning religion in the context of a question about values. But to bring data into it, it's reportedly a fact that "None" [0] as a dominant religious self-identity is indeed a newer/increased phenomenon. It would be hard to argue thats that's not a clear measure of shift in values.
