Unless you're the sole earner for a big family with bad benefits, it is not hard at all to live anywhere in the Bay Area at $117K a year. Yes, it might be prudent to make some basic sanity checks on your spending, especially when it comes to housing (IE don't rent a 1BR in the most desirable part of one of the most competitive cities in the world unless you're making bank).
I would argue that the data in this article should actually be used to realize what a good financial decision the Bay Area is for many people. 80% of people are making more than $117K. As someone in tech you should not have a problem climbing well above that.
