This is what unions are for.
I mean, I could probably get any $100k + "equity" gig on AngelList, but I don't feel like taking a ~50% (rough numbers here, it's less than 50%) pay cut. And I know I'm not even close to the only one in my pay bracket.
Greed is more likely.
There is a pretty decent argument that American corporate culture is very happy to screw workers, defend people who screw workers, and commiserate with those who get caught screwing workers.
If it doesn't make sense, and people point this out, just double down and shout the same thing but louder.
Yawn.
But that's not what was being referred to here, no.
A company - in this case, Zenefits - will have its own distinct culture. This is what's being referred to ... not "businesses overall" (although there can be a lot of similarities) ... and certainly nothing at all to do with something like societal culture, much less the culture of a specific demographic or race.
Honestly, the word culture in this context has nothing to do with race.
