Oregon and California were roughly on par. However, the once bustling downtown where you'd normally find people socializing after work, or hanging out, or doing tech-oriented meetups (I.e., the sorts of things that lead to business creation), was beset by 'fiery but peaceful' riots for almost an entire year. Now, the entire industry of after-work social hours, meetups, etc is dead. It is beginning to be revived but on the east side and suburbs, which is more residential and 'suburban' (although east side portland, is definitely more urban than most places). Suburban is okay, but you really need downtowns to create the sort of bustle that leads to that bay area zeitgeist.

One of the underappreciated things about the bay area is that, while it is very suburban, there are several respectably sized downtown cores -- Mountain View, Palo Alto, Redwood City, and of course the Big Kahuna - San Francisco -- all connected by relatively speedy (and from what I understand, much speedier now) rail.

Here's one thing OP might be talking about – the "skyscraper district" of PDX practically emptied out during COVID, precisely because Portland has highly segregated big-B-business and residential districts. The rise of WFH meant that the whole district nearly emptied out overnight – especially anchor tenants like law firms and tech that were most amenable to WFH. Without any residential population in the area, boom: no place for a downtown flagship office.

All of the west coast went insane, really. It was like the entire region had a competition for how crazy and nonsensical they could make the rules.

As a result, basically every west coast city absolutely destroyed itself and will take at least a decade or more to recover… it they every really do.
