At one point, Dagny Taggart confronts Francisco d'Anconia about what she believed to be his corruption. As part of that, they had the following exchange:
"Do you... know Ellis Wyatt?"
"Do you know what this might do to him?"
"Yes. He's the one who's going to be wiped out next.
"Do you... find that... amusing?"
"Much more amusing than the ruin of the Mexican planners."
Obviously, Francisco knew that Ellis Wyatt would presumably join the Strike (which he did). With that said, though, in what sense did he consider this amusing?
