It's easy to get $200k for ANYONE in the NYC/SF. Please re-read the first message from ceras that started this conversation:
"How does high performer compensation compare to high performer compensation at tech companies (who start at, say, $400K-$500k for what I'll call "entry-level high performer")?"
$200k is absolutely achievable, but claiming that ANYONE (and EVERYONE?) is getting it is farcical. The vast majority of developers are making less than that.
The notion that entry-level developers are getting $400k-500k is a joke. Not even quants start at that.

Since you'd apparently like to be an asshole about markets you know nothing about, I'm done with this conversation.
$200k is a classic "senior" package. It's good but it's nothing outstanding.
No offense intended but finance comp doesn't stop at $180k, you're not looking at the right place or you don't have the profile.
Finance you're typically looking at $180k total comp.
