While Sheldon sees money as a means to an end, Benjamin sees it as an end in and of itself. That suggests that Benjamin is something of an ascetic—one who refrains from indulgence, often for religious reasons—while Sheldon is a hedonist. That portrayal suggests that there is a kind of moral purity to Benjamin’s pursuit of money. He wants money, Harold suggests, not because he’s materialistic or status-obsessed but because he is devoted, perhaps religiously devoted, to the process of accruing it and to the work itself.
