You're saying the average dev at Meta is making 7 figures?

I'm exaggerating for (poor) comedic effect, as Meta has to pay more to attract people. Every time they've ever tried to recruit me I've lol'd at them and said I would never work there under any circumstances.

There are quite a few making that much yearly but not the average. Median swe at meta is almost surely >1MM net worth at least and maybe even 2.
