IIRC Carnegie was the original archetype of the rapacious union-busting wage-suppressing monopolistic billionaire robber baron, and Mellon was all that plus a corrupt self-dealing all-but-impeached laissez-faire Treasury-secretary-cum-megabanker whose deflationary and protectionist response to the Wall Street Crash caused unemployment and destitution on a historic scale.
But yeah this Griffin guy could give the place a bad name. (Full disclosure, I did a postdoc at the SCS.)
