The climate isn't very good for the people in the indeed marketplace. I looked up the indeed in my home town (admittedly not SV) and the jobs were almost entirely below $30K/yr, in the service sector, very low paying receptionist, driver, retail, part time no benefits type of jobs.

True, someone needs to answer the phone and drive trucks in San Jose... just they can't afford to live there on receptionist or delivery driver pay. So there's job openings.

Its a "top 50 worst places to live for working poor" list calculated by finding where working poor cannot live or work anymore, so the jobs go unfilled.

Why are you sure it's the opposite? From the site:

> Here's the number of unemployed per job posting for the 50 most populous metropolitan areas in the U.S.

The title is even "Job Competition" so it's likely the chart is listing the most competitive cities for jobs.
