You're solidly upper class if you work at big tech. Nadella isn't trying to lead people making $42,800/year where a 6.5% decrease in salary can literally be the difference in homelessness. He is trying to lead wealthy software developers where $20k is painful but not life-altering.
It's a bigger issue that the median American salary leaves practically no room for someone to cut their income due to performance. If the only way to survive is to constantly lie about your performance to get an extra couple of bucks, people will do that regardless of what the CEO says or does.
Ideally, we would live in society where everyone had slack in their compensation. This would let more CEOs lead by example.
