I can’t find anything on a quick Google that shows differences between 1980 and present. I did find this though: https://endhomelessness.org/homelessness-in-america/homeless...

That site states homelessness across the country is down 12% from 2007 - 2019, but it is up 9% in California in the same time period.

I think this validates asking the question of whether or not tech has been detrimental to general human welfare in the state of California.
