If you're willing to live a bit further out (like Milpitas/Santa Clara), you can live somewhere for under/around 2000, which (when split with a spouse/partner/roommate) can be reasonable given the salaries in the area.
Looks like I'd have to live with roommates if I moved out there.
Sure, a single guy can rent a single room and walk everywhere. Add in wife and kids and you need three rooms, a car, somewhere to park it. Schooling, activities, shoes and clothes, stuff...suddenly 140k isn't looking too flash anymore.
Assume you're making 140k, after 10% retirement contribution and CA taxes leaves about $6400 per month net. With the average 1 bd apartment at $3200 now that's half your take home wage. Leaving $3200 per month is $800 / week. Or $20.00 an hour at 40 hours. Given typical start-up hours and not even counting the typical food/internet/car expenses. So, if you want to look at it as an all-in after expenses, yeah, even that kind of salary can feel like minimum wage. The economics of minimum wage here in SF are a LOT worse...
EDIT: And some that may not all be income tax? E.g. in Ontario one pays fed income tax, provincial income tax, Canada Pension Plan, Employment Insurance, and a few other I may have forgotten. In London, UK one pays income tax, national insurance, and council tax (property tax paid by property occupiers).
And for all that, we get to pay for our own health care and retirements too!
That said, I'd believe that if you include expenses like health care your net pay would be ~40% less than your gross pay. :P
Is this really true? Seems far-fetched. Isn't that $20-30k higher than the Google base starting salary?
