I don’t get why people keep saying this, it’s like they want companies to pay employees less. No one goes around saying “Investment Banking, now that’s a bubble, no way they can keep paying their employees that much!” (Goldman Sachs revenue / employee over $1.1 million)
Presumably the person commenting on HN is in fact an employee and not like Mark Zuckerberg in disguise, though I guess it would make more sense if the people saying this were startup founders angry at having to compete for talent a FAANG wage levels.
