Earlier quoted context omitted.
Most people who think of 400K (or even 200K in some previous discussions) as "outlier pay" are probably just not familiar with big tech pay and how much revenue they earn per engineer.
> how much revenue they earn per engineer That does not necessarily correlate with salary. At least it doesn't outside of SV.
If I'm making a $1M profit on you, I'll be willing to pay you up to a high fraction of this amount if I have to. Financially, even if I pay you $950K, I'm still making money. Assuming my business scales, I'd hire as many engineers like you as possible, and pay them the same. Why not? I'm making a profit for each one. Great deal for me.
Of course, if you're willing to work for $100k, I'd rather pay you that instead. Hell, I'd rather you worked for me for free!
