It would appear that they pay their employees fairly well, as seen in this old job posting [1] (not all levels will make this much of course but it gives you a general idea, almost 300k a year is a lot even for a staff engineer).

$275,000 is almost $23,000 a month. Take that times N amount of employees, and other business overhead, and suddenly $80k a month is literally peanuts.
