Yeah I make 100k and live in Los Angeles sometimes I can't eat food I work remote so my coworkers outside cifornia don't have it too bad. But despite 30 years of experience I'm hardly worth enough to this society to let me eat food or have a roof over my head. 100k is about average for LA but at one point I had a job that paid me only 45k with no benefits demanding I generate a sentiment analysis system I literally had to stop eating to make my rent on that low pay. But in LA engineers are treated like worse than dogs, we have no social currency and if you work for an LA company they expect 140 hours for 40 hours pay far below market average.
You should be able to get more but it would probably require moving to Riot, Snap or Google. You would want multiple offers etc... I would go the personal network approach if possible with 30 years experience.
PhD adds about 25k-40k to the figure, depending on industry.
