You do realize that valuing equality in itself to any extent at all is always (because of opportunity cost at least) an example of this:

People have been demonstrably willing to make everyone live at a lower standard of living rather than let a tiny minority grow obscenely rich and everyone else be moderately well off.

But I agree with you in sense. Historically lots of horrible people have vastly overpaid (often in blood) and overvalued that particular good according to my values too.
