You're missing the point: in a city where a cup of coffee costs at least $3 and a small condo runs close to a million dollars, the numbers I'm talking about aren't
arrogant, they're just life.
The top-end engineer salary of $160k doesn't go very far here, right now. I'm sure that the distance it goes feels like a lot when you're 23 and one foot out of the dorm room, but when you get older and start wanting to have an adult life (children, saving for retirement, maybe buying a place), it isn't even remotely enough.
$250k, in San Francisco, will rent you a market-rate, one-bedroom apartment ($4k, until they raise the rent next year), and let you live a pretty good lifestyle as a single person: you'll have something like $10k per month after taxes. If you're frugal, and don't go out much, you can get by on maybe $2k a month in expenses. That leaves $8k to save, invest, spend on children, etc.
We aren't talking about big, glamorous lifestyles here.
