At a personal level, a lot, if not most, billionaires never risked anything the vast majority of their employees would have to risk. They were either already rich-enough (or _very_ rich like Bezos), or from families that can support them if something fails. At a company / systemic level, if say Musk or Bezos fail right now, their companies might be at risk and that can lead to thousands of people unemployed. But they already reaped the fruits high reward you're talking about. And a LOT of people take the risks you're talking about, since new businesses are started everyday. But we're talking about billionaires in this context, and the current crop took a risk that the general population would consider it negligible.
