This would require them being not completely paranoid about the poors stealing all their nice things and feeling like they're being ripped off by paying the poors more than they're worth. Being super rich poisons your mind and so they'll be suckered in by meritocracy and protestant work ethic type stuff that makes them think people need to work non stop to deserve a decent life. So this type of idea, while resulting in a better outcome for them, would seem unappealing because they'd see it as just paying for everyone else to jerk around.

Plus their rich friends who they compare themselves to would make fun of them for making such bad business decisions
