Conor should be jealous of Floyd.
Floyd is basically a scam artist, he has made a huge amount of money based off of his fighting skills despite any purple belt easily choking him out. If more people had actual martial knowledge boxing would be widely ridiculed and nobody would pay to see two guys agree to only punch like some sort of moronic robot.
When you can live lavishly like Floyd does and it's based on what's only relevant due to the ignorant masses, then yeah. Feeling bitter about it is a good thing, it's an objective wrong with the world.
