I think one of the major things you learn as you get older is that there is a huge abundance of people who say the right thing, and a much smaller group of people who do the right thing.
The internet made this even worse by celebrating people who only have to say the right thing.
This would be more convincing if there was any agreement on what the right thing supposedly is.
The major lesson I myself learned as I got older is that “you should do the right thing” is a rephrasing of “you should do what I want you to do”.
