San Francisco tech salaries are not representative for the entire US tech industry. And on top of that, San Francisco salaries drive up housing prices, so i'm not sure if working in SF results in a higher discretionary income.
I just checked and in EU big cities like Munich, tech salaries are also around 1.0x-1.2x GPD per capita, making EU just as bad as Toronto. Man, the US is really in a league of its own for tech wages.
You want median individual income, since median is what was under discussion.
