Well, since you live in California, you know ... it’s become very much a two-tiered society: the haves and have-nots.
And it’s gotten worse now that property values have skyrocketed.
So they need to keep building more and more of these 5 story apartment/condo buildings, and other complexes with hundreds of units. I call them civilian barracks. The traffic will eventually become all but totally gridlocked. They know this and that's when they'll force people out of their cars or severely restrict their use.
Bottom line, they allowed in WAY too many people in an area with limited space. In the future, look for S.CA landscape to be filled with 5-10-20 story buildings for the low wage servant class.
