It's all about Cost of Living. A $150k base salary really doesn't get you much more than an average-ish life in San Francisco.
It's whatever, I'm working to move industries. I just look at these numbers for INTERNS and realize I've almost spent a decade treading water with nothing to show for it...all because I picked the wrong major in college.
Extremely disheartening and shame inducing to realize I can't even compete with a college kid on renting an apartment.
this equation is often true for non-family people I know: SFRent - EBRent <= OwningCar
for family people renting bigger spaces, the equation then might look like: SFRent - EBRent >= OwningCar
An hour each way (20 minutes for first and last mile, 40 minute train ride) will save you maybe 30%.
