I agree, they sometimes exchange dignity for money.

In fact, it is not-my-wild guess that the probability of stopping a homicide steeply decreases with the amount of money given to look the other way. For some, even their sister's. Go figure for a job in tech.

So if they were nicer would they reduce their employee costs then? They justify their culture with I'm guessing handy-wavy justifications of business success?

The matter is not being nicer for the sake of it, but more not being a bunch of cultish, indoctrinating, out-of-touch-with-the-world, fake-no-nonsense people. I also tend to judge very negatively people who are "nice" or "not nice" depending on the economic benefit they get from their conduct.
