You're linking conservative think-tanks, not the original source from the smithsonian.

If you'd look at the original infographic, it's about which norms and values are considered "default" in the US, inherited from (white) European values.

With "Hard work" in specific:

> Protestwant Work Ethic

> * Hard work is the key to success

> * Work before play

> * "If you didn't meet your goals, you didn't work hard enough"

And I'm sorry but the notion that these are human-invented norms and values, not "laws of the universe", is pretty fucking milquetoast.

If you genuinely believe all failures at your job are the result of you not hustle-grinding hard enough, that not even a single element contributing to those failures has been out of your control, I have a bridge to sell you.
