“Better moral values” is an interesting phrase, since moral values are the thing by which you’d judge if a thing is better or worse, which just means that better values are those that are closer to whatever one’s own values are.

It seems to me that it should look like this is the case to a typical person regardless of where people’s morals go, because the average person can be expected to have the average values of their time (otherwise how would those be the average values?), and as such, a typical person is going to see a world that mostly agrees with them on what is fundamentally right and wrong, but which historically did not and which eventually changes into values close to their own with time, without there needing to be any kind of arc or force of history that shape’s people’s values towards a given conclusion.

These days there’s the possibly that a manager might just use an AI for response and not consider the implications if the tone looks professional at a glance, perhaps. There’s something that feels AI-ish about it anyway, but that could simply be the corporate “professional” writing style I suppose.
