Hate if you do, hate if you don't.
If there were no tech jobs, people here would complain that they don't have them.
If there are tech jobs, they complain that there are too many, when in reality they are complaining because they are missing out.
I do suspect that there would be different people complaining in those two cases (with some overlap, sure).
Either way, the complains are pretty irrational. I live in San Francisco, where all the property owners are thrilled that their home value has surged in the past couple decades. Take away all the tech jobs, and see what happens to those home values... Can't have your cake and eat it too.
