This sounds like what happened in the SFbay area(south bay/pennisula), I grew up there and it used to be a great place to live, center left politics, lots of families and a diverse set of industries with many middle class opportunities. right around 10-15 years ago things started to change dramatically for the worse, housing and costs everywhere skyrocketed, homeless population exploded, politics veered hard left. Most of my friends from high school(90%) were forced to leave due to rents going from $1k a month to $3k a month for a 1-2 bdrm apts. Those that owned houses also moved as they were fed up with crime and could get a way better house somewhere else. Middle class jobs all disappeared from the area, families also left, the neighborhoods I lived in San Jose (rose garden/willow glen) had barely any kids for my daughter to play with as there were no families anymore, the rose garden neighborhood had 0 kids on the street, the willow glen neighborhood had 1 family w/ kids who moved away during the pandemic.

I was lucky and making really good money in tech but was devastated by how the area I grew up in had turned into a nightmare and everyone I know (even family) leaving the area. I too ended leaving as the cost vs. quality of life didn't make any sense and I couldn't see my family living in a place I didn't even recognize anymore. Most people don't talk about it but there is a huge diaspora of bay area residents due to the stuff mentioned above and it breaks my heart to think we will most likely never return and familiy/friends I expected to spend the rest of my life with all leaving.
