I like feel they're actually under-inflated (at least for comparing high paid workers in both places) because of equity.

The company I work at has rallied many times over 100% since I joined a bit over a year ago. I could sell my equity and "semi-retire" 30+ years early, working when/if I feel like it and not eat really into my savings

It wasn't some grand plan to join a company that would do well during a pandemic, but I did intentionally choose a public company since saying in the tech sector has exploded would be an understatement, and I wanted equity in that.

I'm guessing a lot of people who joined FAANG companies in the last few years are all probably sitting on enough to start thinking about that.

There are those who feel this is a bubble and not sustainable... maybe? But the way I see it is, even if this is the bubble before the next dot com era-style bust, it's better to have a position in it provided by my work and cashing out along the way, than not and end up losing my job anyways.
