sorry, I am not going to bother reading the rest of your comment before writing this reply because reading this part stopped me immediately.

Gentrification and displacement has been a growing issue for decades. Especially in California, people who grow up here can't afford to stay here and end up moving from high cost coastal areas to exurbs in the central valley or inland empire or just leave the state entirely for places like arizona, nevada, texas, or beyond. These are the places that have been growing most over the past couple of decades. Population in the high-cost areas may be increasing too (or at least staying the same) but that's because higher-income people who can afford it are willing and able to move there.
