Hiring good people is not cheap! "Mozilla's highest-paid official, chairperson Mitchell Baker, now enjoys a pay package that tops $1 million. In 2014, she got a $400,000 base salary, a $594,000 bonus and some other benefits that pushed total compensation to $1,035,114.Nov 30, 2015"
I fail to see how north of 80k$/mo is a reasonable salary. Maybe things are more costly in America, with private insurance and whatnot, but where I live (Italy) few people earn more than €10k/mo after taxes.
I know about 20 years ago, Ben & Jerry's tried to hire a CEO for a reasonable salary and decided they couldn't make it work.
So maybe it really does make sense.
