As others have pointed out, with benefits, taxes, etc the actual salary is going to by way under that.
But I don't see why you're getting downvoted either. The income inequality in places like SV and Seattle/Redmond is insane. People working "normal jobs" struggle to get by and often have to commute further and live way outside the city just to survive.
It gets even more ass-backwards because public transport hubs are way more expensive to live near and, once again, only highly paid individuals can live near them (and therefore ditch their cars potentially saving even more money, where as the not so well off have a car requirement because .. American's transportation failure. And before you give me that "American is too spread out for rail" shit, Russia has three high speed rails and St Petersburg has the 2nd largest tram network in the world).
You're pointing to a very real problem. If there was plenty of housing and transport, those wages wouldn't put the strain they do on every one else. But there isn't and they do. Working remotely would actually be way better because at least they're not in the SV area.
And to rant a little more, a high end engineer that would cost $200k in Washington/California (maybe NYC too) would start at 50k euro in Berlin. They'd top out around 70k euro at the most. Even for really highly skilled positions, Germany tends to have way less income inequality and flats are also way more affordable for everyone.
